    Compact Disc is still the de facto standard for audio recordings, although its place for other multimedia recordings and optical data storage has largely been superseded by DVD. DVD (initially an acronym of "Digital Video Disc", then backronymed as "Digital Versatile Disc" and officially just "DVD") was the mass market successor to CD.

    Many types of optical discs are factory-pressed or finalized write once read many storage devices and would therefore not be effective at spreading computer worms that are designed to spread by copying themselves onto optical media, because data on those discs can not be modified once pressed or written.

    A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. 130 mm (5.25 in) and 90 mm (3.5 in) discs are the most common sizes. In 1983, just a year after the introduction of the compact disc , Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable ...

  9. Optical storage media writing and reading speed - Wikipedia

    en.wikipedia.org/wiki/Optical_storage_media...

    In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
