85-532: CD-RW ( Compact Disc-Rewritable ) is a digital optical disc storage format introduced by Ricoh in 1997. A CD-RW compact disc (CD-RWs) can be written, read, erased, and re-written. CD-RWs, as opposed to CDs, require specialized readers that have sensitive laser optics. Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW. CD-ROM drives with a "MultiRead" certification are compatible. CD-RWs must be erased or blanked before reuse. Erasure methods include full blanking where

170-431: A polycrystalline structure and reflective properties in its original state. When writing the laser beam uses its maximum power ( 8-14 mW ) to heat the material to 500–700 °C causing material liquefaction . In this state, the alloy loses its polycrystalline structure and reflectivity and assumes an amorphous state. The lost reflectivity serves the same function as bumps on manufactured CDs. The polycrystalline state of

255-399: A CD-RW has a minimum writing speed under which the discs cannot be recorded, based on the phase change material's heating and cooling time constants and the required laser energy levels. Despite this, some professional audio CD recorders, such as those made by Tascam, use special techniques to bypass these limitations and can record high speed (but not ultra speed) discs in realtime. Since

340-459: A basis to analyse the melting conditions. The Lindemann criterion states that melting occurs because of "vibrational instability", e.g. crystals melt; when the average amplitude of thermal vibrations of atoms is relatively high compared with interatomic distances, e.g. < δu > > δ L R s , where δu is the atomic displacement, the Lindemann parameter δ L ≈ 0.20...0.25 and R s

425-474: A broader form of political censorship . Over the years YouTube has grown to become a website with user generated media. This content is oftentimes not mediated by any company or agency, leading to a wide array of personalities and opinions online. Over the years, YouTube and other platforms have also shown their monetary gains. In 2020, the top 10 highest earning YouTube content creators each generated over 15 million dollars. Many of these YouTube profiles over

510-513: A copyright violation on TikTok. One example is, accidentally having music playing on a stereo in the background or recording a laptop screen playing a song. Online magazines or digital magazines are one of the largest targets for copyright issues. According to the Audit Bureau of Circulations report from March 2011, the definition of this medium is when a digital magazine involves the distribution of magazine content by electronic means; it may be

595-493: A decrease in newspaper industry employment, with only about 40,000 people working in the workforce currently. Alliance of Audited Media & Publishers information during the 2008 recession, over 10% of print sales are diminished for certain magazines, with a hardship coming from only 75% of the sales advertisements as before. However, in 2018, major newspapers advertising revenue was 35% from digital ads. In contrast, mobile versions of newspapers and magazines came in second with

680-688: A decrease of cable TV services to about 59%, while streaming services are growing at around 29%, and 9% are still users of the digital antenna. TV Controllers now incorporate designated buttons for streaming platforms. Users are spending an average of 1:55 with digital video each day, and only 1:44 on social networks. 6 out of 10 people report viewing their television shows and news via a streaming service. Platforms such as Netflix have gained attraction due to their adorability, accessibility, and for its original content. Companies such as Netflix have even bought previously cancelled shows such as Designated Survivor , Lucifer , and Arrested Development . As

765-450: A fully digital, paperless society is accompanied by the fear that we may soon—or currently—be facing a digital dark age , in which older media are no longer accessible on modern devices or using modern methods of scholarship. Digital media has a significant, wide-ranging and complex effect on society and culture. A senior engineer at Motorola named Martin Cooper was the first person to make

850-463: A high powered and fast specification drive. For these reasons, older CD-RW drives that lack appropriate firmware and hardware are not compatible with newer, high-speed CD-RW discs, while newer drives can record to older CD-RW discs, provided their firmware correct speed, delay, and power settings can be appropriately set. The actual reading speed of CD-RW discs, however, is not directly correlated or bound to speed specification, but depends primarily on

935-475: A huge growth of 135%. The New York Times has noted a 47% year of year rise in their digital subscriptions. 43% of adults get news often from news websites or social media, compared with 49% for television. Pew Research also asked respondents if they got news from a streaming device on their TV – 9% of U.S. adults said that they do so often. Digital media has also allowed individuals to be much more active in content creation . Anyone with access to computers and

1020-461: A middle-ground between online and offline storage schemes. Before CD-RW technology, in 1990 a standard for magneto-optical recordable and erasable CDs called CD-MO was introduced and set in the Orange Book, part 1 as a CD with a magneto-optical recording layer. The CD-MO standard allowed for an optional non-erasable zone on the disc that could be read by CD-ROM units. Data recording (and erasing)

1105-494: A multi-session disc has a corresponding lead-in, PMA, PA and lead-out. When the session is closed TOC information in the PMA is written into a lead-in area and the PCA and PMA are logically eliminated. The lead-out is created to mark the end of the data in the session. Like a CD-R, a CD-RW has hardcoded speed specifications which limit recording speeds to fairly restrictive ranges. Unlike a CD-R,

1190-458: A new period in human history known as the Information Age or the digital revolution . The transition has created some uncertainty about definitions. Digital media, new media , multimedia , and similar terms all have a relationship to both the engineering innovations and cultural impact of digital media. The blending of digital media with other media, and with cultural and social factors,

1275-521: A phone call on April 3, 1973. He decided the first phone call should be to a rival telecommunications company saying "I'm speaking via a mobile phone". Ten years later, Motorola released the Motorola DynaTAC , the first commercially available mobile phone. In the early 1990s Nokia released the Nokia 1011 , the first mass-produced mobile phone. The number of smartphone users has increased dramatically, as has

1360-423: A replica. This definition can be considered outdated now that PDF replicas of print magazines are no longer common practice. These days digital magazines refer to magazines specifically created to be interactive digital platforms such as the internet, mobile phones, private networks, iPad, or other devices. The barriers to digital magazine distribution are thus decreasing. However, these platforms are also broadening

1445-424: A significant, wide-ranging and complex impact on society and culture. Digital media platforms like YouTube work through a triple-product business model in which platforms provide information and entertainment ( infotainment ) to the public often at no cost, while simultaneously capturing their attention, and also collecting user data to sell to advertisers. This business model aims to maximize consumer engagement on

1530-617: A significantly broad and complex impact on society and culture. Combined with the Internet and personal computing , digital media has caused disruptive innovation in publishing, journalism, public relations, entertainment, education, commerce and politics. Digital media has also posed new challenges to copyright and intellectual property laws, fostering an open content movement in which content creators voluntarily give up some or all of their legal rights to their work. The ubiquity of digital media and its effects on society suggest that we are at

1615-432: A slight superimposed sinusoidal excursion of 0.3 µm at a frequency of 22.05  kHz . In addition a 1 kHz frequency modulation is applied to provide the recorder with an absolute time reference. Groove width is 0.6  μm and pitch of 1.6 μm . The media for CD-RW has the same layers as CD-R media. The reflective layer is, however, a silver - indium - antimony - tellurium ( AgInSbTe ) alloy with

1700-528: A standard set of conditions, the melting point of a substance is a characteristic property. The melting point is often equal to the freezing point . However, under carefully created conditions, supercooling, or superheating past the melting or freezing point can occur. Water on a very clean glass surface will often supercool several degrees below the freezing point without freezing. Fine emulsions of pure water have been cooled to −38 °C without nucleation to form ice . Nucleation occurs due to fluctuations in

1785-464: A system of devices that could be used to help scientists, doctors, and historians, among others, to store, analyze and communicate information. Calling this then-imaginary device a " memex ", Bush wrote: The owner of the memex, let us say, is interested in the origin and properties of the bow and arrow. Specifically, he is studying why the short Turkish bow was apparently superior to the English long bow in

1870-497: A system of ones and zeroes that are combined to make hundreds of characters. The 1s and 0s of binary are the "digits" of digital media. While digital media did not come into common use until the late 20th century, the conceptual foundation of digital media is traced to the work of scientist and engineer Vannevar Bush and his celebrated essay " As We May Think ", published in The Atlantic Monthly in 1945. Bush envisioned

1955-455: Is elemental sulfur , whose viscosity increases in the range of 160 °C to 180 °C due to polymerization . Some organic compounds melt through mesophases , states of partial order between solid and liquid. From a thermodynamics point of view, at the melting point the change in Gibbs free energy ∆G of the substances is zero, but there are non-zero changes in the enthalpy ( H ) and

2040-402: Is Tucker Carlson leaving Fox News due to his controversial opinions and moving over to X. This has sparked debate surrounding topics such as free speech and hate speech. Digital media encompasses numerical networks of interactive systems that link databases, allowing users to navigate from one bit of content or webpage to another. Because of this ease, digital media poses several challenges to

2125-467: Is because a series of computer technologies protect the digital content being created and transmitted. The Digital Millennium Copyright Act (DMCA) provides safety to intermediaries that host user content, such as YouTube, from being held liable for copyright infringement so long as they meet all required conditions. The most notable of which is the " notice and take down " policy. The policy requires online intermediaries to remove and/or disable access to

2210-460: Is being used. If the content is non-fiction, it is more likely to fall under fair use than if the content is fiction. The third factor is how much of the copyrighted content is in use. Small amounts of copyrighted content are more likely to be considered fair. The last factor is, whether the use of copyrighted content earns money or affect the value of the content. Misplaced Pages uses some of the most common open licenses, Creative Commons licenses, and

2295-432: Is due to the development of the internet as well as the way in which users interact with media today. As more users join and use social media sites, the relevance of content creation increases. The release of technologies such mobile devices allow for easier and quicker access to all things media. Many media creation tools that were once available to only a few are now free and easy to use. The cost of devices that can access

2380-552: Is estimated that in the year 1986 less than 1% of the world's media storage capacity was digital and in 2007 it was already 94%. The year 2002 is assumed to be the year when human kind was able to store more information in digital than in analog media (the "beginning of the digital age "). Though they used machine-readable media, Babbage's engines, player pianos, jacquard looms and many other early calculating machines were themselves analog computers , with physical, mechanical parts. The first truly digital media came into existence with

2465-426: Is one-half of the inter-atomic distance. The "Lindemann melting criterion" is supported by experimental data both for crystalline materials and for glass-liquid transitions in amorphous materials. The Born criterion is based on a rigidity catastrophe caused by the vanishing elastic shear modulus, i.e. when the crystal no longer has sufficient rigidity to mechanically withstand the load, it becomes liquid. Under

2550-468: Is so good that users cannot help but post it on their social media, they get a lot of "earned media". They win the credibility of the media compared to other forms of credibility, becoming more transparent. Codes and information by machines were first conceptualized by Charles Babbage in the early 1800s. Babbage imagined that these codes would give him instructions for his Motor of Difference and Analytical Engine, machines that Babbage had designed to solve

2635-453: Is sometimes known as new media or "the new media." Similarly, digital media seems to demand a new set of communications skills, called transliteracy , media literacy , or digital literacy . These skills include not only the ability to read and write—traditional literacy —but the ability to navigate the Internet, evaluate sources, and create digital content. The idea that we are moving toward

2720-490: Is the only known exception to the general rule. Helium-3 has a negative enthalpy of fusion at temperatures below 0.3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0.8 K. This means that, at appropriate constant pressures, heat must be removed from these substances in order to melt them. Among the theoretical criteria for melting, the Lindemann and Born criteria are those most frequently used as

2805-510: Is the short video-sharing app TikTok . TikTok is a social media app that allows users to share short videos up to one minute in length, using a variety of visual effects and audio. According to Loyola University 's Chicago School of Law, around 50% of the music used on TikTok is unlicensed. TikTok has several music licensing agreements with various artists and labels, creating a library of fair and legal use of music. However, this does not cover all content for its users. A user could still commit

2890-429: Is used to lock material. This allows users to apply the media content to specific cases. DRM allows movie producers to rent at a lower price. This restricts the movie rental license length, rather than only selling the movie at full price. Additionally, DRM can prevent unauthorized modification or sharing of media. Digital media copyright protection technologies fall under intellectual property protection technology. This

2975-705: The GNU Free Documentation License . Open licenses are one aspect of a broad open content movement that advocates for the reduction or removal of copyright restrictions from software, data, and other digital media. To facilitate the collection and consumption of such licensing information and availability status, tools like the Creative Commons Search engine are used mostly for web images, and Unpaywall , or used for scholarly communication . Additional software has been developed to restrict access to digital media. Digital rights management (DRM)

3060-532: The SH-224DB (2013) and Blu-Ray writers such as the LG BE16NU50 (2016) have downgraded the backwards compatibility to CD-RW UltraSpeed (24× Z-CLV). Slim type optical drives are subject to physical limitations, thus are not able to attain rotation speeds of half-height (desktop) optical drives. They usually support CD-RW writing speeds of 16× or 24× Z-CLV in zones of 10× CLV, 16× CLV, 20× CLV and 24× CLV towards

3145-447: The entropy ( S ), known respectively as the enthalpy of fusion (or latent heat of fusion) and the entropy of fusion . Melting is therefore classified as a first-order phase transition . Melting occurs when the Gibbs free energy of the liquid becomes lower than the solid for that material. The temperature at which this occurs is dependent on the ambient pressure. Low-temperature helium

3230-459: The public domain . By doing this, creators are giving up certain legal rights regarding their content. Fair use is a doctrine of the US Copyright Law that allows limited use of copyrighted materials without the need to obtain permission. There are four factors that make up fair use. The first, Purpose, refers to what the content is being used for. The second factor is what copyrighted content

3315-456: The Apple App store. These are all opportunities for digital marketing efforts. A smartphone user is impacted with digital advertising every second they open their Apple or Android device. This further evidences the digital revolution and the impact of revolution. This has resulted in a total of 13 billion dollars being paid out to the various app developers over the years. This growth has fueled

3400-476: The CD-RW discs need to be blanked before recording data, writing too slowly or with too low energy on a high speed unblanked disc will cause the phase change layer to cool before blanking is achieved, preventing the data from being properly written. Similarly, using inappropriately high amounts of laser energy will cause the material to overheat and be insensitive to the data, a situation typical of slower discs used in

3485-494: The Internet can participate in social media and contribute their own writing, art, videos, photography and commentary to the Internet, as well as conduct business online. The dramatic reduction in the costs required to create and share content have led to a democratization of content creation as well as the creation of new types of content, like blogs , memes , and video essays . Some of these activities have also been labelled citizen journalism . This spike in user-created content

Combined with the World Wide Web and the Internet , digital media has transformed 21st century society in a way that is frequently compared to the cultural, economic and social impact of the printing press . The change has been so rapid and so widespread that it has launched an economic transition from an industrial economy to an information-based economy, creating

3740-472: The analog special effects, stunt, and animation industries in Hollywood. It has imposed painful costs on small movie theaters, some of which did not or will not survive the transition to digital. The effect of digital media on other media industries is similarly sweeping and complex. Between 2000 and 2015, the print newspaper advertising revenue has fallen from $ 60 billion to a nearly $ 20 billion. Even one of

3825-416: The book industry, and digital textbooks and other media-inclusive curricula are changing primary and secondary education. In academia, digital media has led to a new form of scholarship, also called digital scholarship , making open access and open science possible thanks to the low cost of distribution. New fields of study have grown, such as digital humanities and digital history . It has changed

3910-421: The broken bonds form a percolation cluster with T g dependent on quasi-equilibrium thermodynamic parameters of bonds e.g. on enthalpy ( H d ) and entropy ( S d ) of formation of bonds in a given system at given conditions: where f c is the percolation threshold and R is the universal gas constant. Although H d and S d are not true equilibrium thermodynamic parameters and can depend on

3995-510: The channel such as business or person managing their online presence Earned media denotes public relations media channels like television, newspapers, blogs, or video sites that do not require direct payment or control by marketers but are included because viewers, readers, or users are interested in them. Free media is essentially online word of mouth, typically in "viral" trends, mentions, shares, retweets, reviews, recommendations, or content from third-party websites. When one's product or service

4080-570: The commercial landscape. While Android and iOS both dominate the smartphone market. A study By Gartner found that in 2016 about 88% of the worldwide smartphones were Android while iOS had a market share of about 12%. About 85% of the mobile market revenue came from mobile games. The impact of the digital revolution can also be assessed by exploring the amount of worldwide mobile smart device users there are. This can be split into 2 categories; smart phone users and smart tablet users. Worldwide there are currently 2.32 billion smartphone users across

4165-465: The content in question when there are court orders and/or allegations of illegal use of the content on their site. As a result, YouTube has and continues to develop more policies and standards that go far past what the DMCA requires. YouTube has also created an algorithm which continuously scans their cite to make sure all content follows all policies. One digital media platform known to have copyright concerns

Even below its melting point, quasi-liquid films can be observed on crystalline surfaces. The thickness of the film is temperature-dependent. This effect is common for all crystalline materials. This pre-melting shows its effects in e.g. frost heave, the growth of snowflakes, and, taking grain boundary interfaces into account, maybe even in

4335-405: The creation of this memex would be the work of scientists after World War II. Though the essay predated digital computers by several years, "As We May Think" anticipated the potential social and intellectual benefits of digital media and provided the conceptual framework for digital scholarship , the World Wide Web , wikis and even social media . It was recognized as a significant work even at

4420-565: The current copyright and intellectual property laws. The ease of creating, modifying, and sharing digital media can influence copyright enforcement challenging and many copyright laws are widely seen as outdated. Under current copyright law, common Internet memes are generally illegal to share in many countries. Legal rights can be unclear for many common Internet activities. These include posting pictures from someone else's social media account, writing fanfiction , or covering and/or using popular songs in content such as YouTube videos. During

4505-471: The development of millions of software applications. Most of these apps are able to generate income via in app advertising. Gross revenue for 2020 is projected to be about $ 189 million. Compared with print media , the mass media , and other analog technologies, digital media are easy to copy, store, share and modify. This quality of digital media has led to significant changes in many industries, especially journalism, publishing, education, entertainment, and

4590-440: The disc forms the trenches. The scanning signal when reading is created by strong or weak reflection of the laser beam. To erase the disc, the write beam heats the amorphous regions with low power to about 200 °C . The alloy is not melted, but returns to the polycrystalline state and is again reflective. During and after a disc authoring the distribution of data on the CD-RW varies. The following areas are present: Each session on

4675-508: The entire surface of the disc is erased and fast blanking where only metadata areas, such as PMA , TOC and pregap , are cleared. Fast blanking is quicker and usually sufficient to allow rewriting the disc. Full blanking removes all traces of the previous data, and is often used for confidentiality purposes. CD-RWs can sustain fewer re-writes compared to other storage media (ca. 1,000 compared up to 100,000). They are ideally used for test discs (e.g. for CD authoring ), temporary backups, and as

4760-547: The internet becomes more and more prevalent, more companies are beginning to distribute content through internet only means. Indeed, young people today are increasingly likely to use TikTok over Google, television or newspapers for their news. With the loss of viewers, there is a loss of revenue but not as bad as what would be expected. As of 2024 there has also been a wave of those considered too controversial by main-stream media moving over to online platforms such as X (formerly Twitter) to keep spreading their messages. One instance

4845-439: The larger issues that have occurred concerning digital media copyright. The piracy of digital media, such as film and television, directly impacts the copyright party (the owner of the copyright). This action can impact the "health" of the digital media industry. Piracy directly breaks the laws and morals of copyright. Along with piracy, digital media has contributed to the ability to spread false information or fake news . Due to

4930-668: The last decade, the concepts of fair use and copyright have been applied to different types of online media. Copyright challenges are spreading to all parts of digital media. Content creators on platforms such as YouTube follow guidelines set by copyright, IP laws, and the platform's copyright requirements. If these guidelines are not followed, the content may get demonetized, deleted, or sued. The situation can also occur when creators accidentally use audio tracks or background scenes that are under copyright. To avoid or resolve some of these issues, content creators can voluntarily adopt open , or copyleft licenses or they can release their work to

In journalism, digital media and citizen journalism have led to the loss of thousands of jobs in print media and the bankruptcy of many major newspapers. But the rise of digital journalism has also created thousands of new jobs and specializations. E-books and self-publishing are changing

5355-420: The movement of glaciers . In ultrashort pulse physics, a so-called nonthermal melting may take place. It occurs not because of the increase of the atomic kinetic energy, but because of changes of the interatomic potential due to excitation of electrons. Since electrons are acting like a glue sticking atoms together, heating electrons by a femtosecond laser alters the properties of this "glue", which may break

5440-401: The music business. The overall effect of these changes is so far-reaching that it is difficult to quantify. For example, in movie-making, the transition from analog film cameras to digital cameras is nearly complete. The transition has economic benefits to Hollywood, making distribution easier and making it possible to add high-quality digital effects to films. At the same time, it has affected

5525-848: The outer edge, of which the highest speed zone depends on availability. Digital media Digital media platforms, such as YouTube , Kick , and Twitch , accounted for viewership rates of 27.9 billion hours in 2020. A contributing factor to its part in what is commonly referred to as the digital revolution can be attributed to the use of interconnectivity. Examples of digital media include software , digital images , digital video , video games , web pages and websites , social media , digital data and databases , digital audio such as MP3 , electronic documents and electronic books . Digital media often contrasts with print media , such as printed books, newspapers and magazines, and other traditional or analog media, such as photographic film , audio tapes or video tapes . Digital media has had

5610-440: The platform. Paid media refers to promotional channels that marketers pay to use, including traditional media (e.g., television, radio, print, or outdoor advertising), online and digital media (e.g., paid search ads, web and social media display ads, mobile ads, or email marketing). This model compels businesses to develop sponsored media then pay social media platforms like Instagram for the right to show such media to customers in

5695-413: The platforms' newsfeeds. These customers become exposed to paid media, sometimes referred to as promoted or sponsored posts. Owned media refers to digital assets and channels that a company or individual controls and manages. This includes websites, social media profiles for example Facebook etc., blogs, and any other content platforms own and operated by the entity. Entity means the owner or controller of

At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid. Substances in the molten state generally have reduced viscosity as the temperature increases. An exception to this principle

6460-441: The start of a new era in industrial history, called the Information Age , perhaps leading to a paperless society in which all media are produced and consumed on computers. However, challenges to a digital transition remain, including outdated copyright laws, censorship , the digital divide , and the spectre of a digital dark age , in which older media becomes inaccessible to new or upgraded information systems. Digital media has

6545-459: The time of its publication. Since the 1960s, computing power and storage capacity have increased exponentially, largely as a result of MOSFET scaling which enables MOS transistor counts to increase at a rapid pace predicted by Moore's law . Personal computers and smartphones put the ability to access, modify, store and share digital media in the hands of billions of people. Many electronic devices, from digital cameras to drones have

6630-530: The typical CD-ROM filesystems, replaced the CD-MO. Rewritable media can, with suitable hardware, be re-written up to 100 000 times . The CD-RW is based on phase change technology, with a degree of reflection at 15–25% , compared to 40–70% for CD-R discs. The properties of the medium and the write and erase procedure is defined in the Orange Book Part III . To maintain a precise rotation speed, tracks have

6715-547: The way libraries are used and their role in society. Every major media, communications and academic endeavor is facing a period of transition and uncertainty related to digital media. Often time the magazine or publisher have a Digital edition which can be referred to an electronic formatted version identical to the print version. There is a huge benefit to the publisher and cost, as half of traditional publishers' costs come from production, including raw materials, technical processing, and distribution. Since 2004, there has been

6800-460: The wide range of literacy and communications skills necessary to use it effectively, have deepened the digital divide between those who have access to digital media and those who do not. The rising of digital media has made the consumer's audio collection more precise and personalized. It is no longer necessary to purchase an entire album if the consumer is ultimately interested in only a few audio files. The rise of streaming services has led to

6885-402: The widespread use of digital media, fake news can receive more notoriety. This notoriety enhances the negative effects fake news creates. As a result, people's health and well-being can directly be affected. Melting Melting , or fusion , is a physical process that results in the phase transition of a substance from a solid to a liquid . This occurs when the internal energy of

6970-474: The world. This figure is to exceed 2.87 billion by 2020. Smart tablet users reached a total of 1 billion in 2015, 15% of the world's population. The statistics evidence the impact of digital media communications today. What is also of relevance is the fact that the number of smart device users is rising rapidly yet the amount of functional uses increase daily. A smartphone or tablet can be used for hundreds of daily needs. There are currently over 1 million apps on

7055-582: The years have a multi camera set up as we would see on TV. Many of these creators also creating their own digital companies as their personalities grow. Personal devices have also seen an increase over the years. Over 1.5 billion users of tablets exist in this world right now and that is expected to slowly grow About 20% of people in the world regularly watch their content using tablets in 2018 User-generated content raises issues of privacy, credibility, civility and compensation for cultural, intellectual and artistic contributions. The spread of digital media, and

7140-458: Was achieved by heating the magneto-optical layer's material (e.g. Dy Fe Co or less often Tb Fe Co or Gd Fe Co ) to its Curie point and then using a magnetic field to write the new data, in a manner essentially identical to Sony's MiniDisc and other magneto-optical formats. Reading the discs relied on the Kerr effect a major format flaw. The rewrite could only be read in special drives and

7225-487: Was incompatible with non-magneto-optical enabled drives. The format was never released commercially, mostly because of incompatibility with standard CD reading units. Early CD-R media contained a similar compatibility flaw. Since the CD-MO was otherwise identical to CDs, the format still adopted a spiral-groove recording scheme, rendering the disc poorly suited as a removable medium for repeated, small-scale deletions and recordings. Some magneto-optical drives and media with
