The collection includes many features for CD, DVD and Blu-ray disc writing such as: creation of audio, data, and mixed (audio and data) CDs; burning CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW, dual layer DVDs, and Blu-ray Discs; support for Track-At-Once and Disc-At-Once recording modes; cue sheet file format support, with Exact Audio Copy ...
The Image Mastering Application Programming Interface, or IMAPI, is a component of Microsoft Windows operating system used for CD and DVD authoring and recording.. Windows applications such as Windows Media Player, Windows Media Center, Windows Movie Maker, Windows DVD Maker, and Windows Explorer use IMAPI to create ISO 9660 and "burn" discs.
The media for CD-RW has the same layers as CD-R media. The reflective layer is, however, a silver-indium-antimony-tellurium alloy with a polycrystalline structure and reflective properties in its original state. When writing the laser beam uses its maximum power (8-14 mW) [6] to heat the material to 500–700 °C causing material liquefaction.
The CD-ROM itself may contain "weak" sectors to make copying the disc more difficult, and additional data that may be difficult or impossible to copy to a CD-R or disc image, but which the software checks for each time it is run to ensure an original disc and not an unauthorized copy is present in the computer's CD-ROM drive.
Russell's first optical disc was distinctly different from the eventual compact disc product: the disc in the player was not read by laser light. A key characteristic of Russell's invention is that a laser is not used for the reading the disc, instead the entire disc or oblong sheet to be read is illuminated by a large playback light source at ...
Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 minutes worth of data. The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data ...
Most optical disc authoring utilities create a disc image and copy it to the disc in one bundled operation, so that end-users often do not know the distinction between creating and burning. However, it is useful to know because creating the disc image is a time-consuming process, while copying the image is much faster.
Burned CD-Rs suffer from material degradation, just like most writable media. CD-R media have an internal layer of dye used to store data. In a CD-RW disc, the recording layer is made of an alloy of silver and other metals—indium, antimony, and tellurium. [20] In CD-R media, the dye itself can degrade, causing data to become unreadable.
