CD-ROM drive
(CD-ROM) A non-volatile optical data storage
medium using the same physical format as audio {compact
discs}, readable by a computer with a CD-ROM drive.
CD-ROM is popular for distribution of large databases,
software and especially multimedia applications. The
maximum capacity is about 600 megabytes. A CD can store
around 640 megabytes of data - about 12 billion bytes per
pound weight.
CD-ROM drives are rated with a speed factor relative to music
CDs (1x or 1-speed which gives a data transfer rate of 150
kilobytes per second). 12x drives were common in April
1997. Above 12x speed, there are problems with vibration and
heat. Constant angular velocity (CAV) drives give speeds up
to 20x but due to the nature of CAV the actual throughput
increase over 12x is less than 20/12.
20x was thought to be the maximum speed due to mechanical
constraints but on 1998-02-24, Samsung Electronics
introduced the SCR-3230, a 32x CD-ROM drive which uses a ball
bearing system to balance the spinning CD-ROM in the drive to
reduce noise.
CD-ROM drives may connect to an IDE interface, a SCSI
interface or a propritary interface, of which there are three
- Sony, Panasonic, and Mitsumi. Most CD-ROM drives can also
play audio CDs.
There are several formats used for CD-ROM data, including
Green Book CD-ROM, White Book CD-ROM and {Yellow Book
CD-ROM}. ISO 9660 defines a standard file system, later
extended by Joliet.

green book cd-rom
(foldoc) | Green Book CD-ROM
A standard CD-ROM format developed by Philips for CD-i.
It is ISO 9660 compliant and uses mode 2 form 2 addressing.
It can only be played on drives which are XA ({Extended
Architecture}) compatible.
Many Green Book discs contain CD-i applications which can
only be played on a CD-i player but many others contain
films or music videos. Video CDs in Green Book format are
normally labelled "Digital Video on CD"
Green Book was obsoleted by White book CD-ROM in March 1994.

white book cd-rom
(foldoc) | White book CD-ROM
A more open CD-ROM standard than
Green Book CD-ROM. All films mastered on CD-ROM after March
1994 use White Book. Like Green Book, it is ISO 9660
compliant, uses mode 2 form 2 addressing and can only be
played on a CD-ROM drive which is XA (Extended
Architecture) compatible. White book CDs are labelled "Video
CD".

yellow book cd-rom
(foldoc) | Yellow Book CD-ROM
A CD-ROM format which is ISO 9660 compliant and uses mode
1 addressing. Discs of this type can be played on most drives
and would be appropriate for most multimedia applications
which have been developed for personal computers.
