CD-ROM drives are rated with a speed factor relative to music CDs. If a CD-ROM is read at the same rotational speed as an audio CD, the data transfer rate is 150 Kbyte/s, commonly called "1×" (with constant linear velocity, short "CLV"). At this data rate, the track moves along under the laser spot at about 1.2 m/s.

A compressed audio optical disc, MP3 CD, or MP3 CD-ROM or MP3 DVD is an optical disc (usually a CD-R, CD-RW, DVD-R or DVD-RW) that contains digital audio in the MP3 file format. Discs are written in the "Yellow Book" standard data format (used for CD-ROMs and DVD-ROMs), as opposed to the Red Book standard audio format (used for CD-DA audio CDs).
A sector is the primary data structure on a CD-ROM accessible to external software (including the OS). On a Mode-1 CD-ROM, each sector contains 2048 bytes of user-data (content) and 304 bytes of structural information. Among other things, the structural information consists of the sector number, the sector's relative and absolute logical position
For the first few years of its existence, the CD was a medium used purely for audio. In 1988, the Yellow Book CD-ROM standard was established by Sony and Philips, which defined a non-volatile optical data computer data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive.
The Voyager Company was a pioneer in CD-ROM production in the 1980s and early 1990s. It was founded in 1984 by four partners: Jon Turell, Bill Becker, Aleen Stein, and Robert Stein in Santa Monica, California, and later moved to New York City. The firm took its name from the Voyager space craft.
Kodak Photo CD and packaging. Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD. Launched in 1991, [1] the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding.
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.
