Optical computer storage

A CD-ROM (, compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains data computers can read, but not write or erase. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs).

Hi-MD is a magneto-optical disc-based data storage format. It was a further development of the MiniDisc. With its release in late 2004, came the ability to use newly developed, high-capacity 1 gigabyte Hi-MD discs, in the same dimensions as MiniDisc. The last recorder and player was discontinued in 2011. Blank discs stopped production in September 2012.

right|thumb|The 21 MB Floptical -inch disk Floptical refers to a type of floppy disk drive that combines magnetic and optical technologies to store data on media similar to standard -inch floppy disks. The name is a portmanteau of the words "floppy" and "optical". It refers specifically to one brand of drive and disk system, but is also used more generically to refer to any system using similar techniques.

DataPlay is an optical disc system developed by DataPlay Inc. and released to the consumer market in 2002. Using tiny (32mm-diameter) disks enclosed in a protective cartridge, it stored 250MB per side and was intended primarily for portable music playback. However, it could also store other types of data using pre-recorded disks and user-recorded disks (and disks that combined pre-recorded content with a writable area). It supported multisession recording. DataPlay Inc. was founded in 1998 by Steve Volk. The company's namesake optical disc won the CES Best of Show award in 2001.
