ABSTRACT
CD-R stands for compact disc-recordable and is the CD equivalent of Sony's component recording video disc burner. It is produced by a one-off CD-read only memory (ROM) write once, read many writers that use different technology to create a CD-ROM than the standard mastering process. CD-Rs are gold in color to distinguish them and are used for short runs, for check discs that can serve as templates to create a standard master duplication disc, and for archiving text or image files. The CD-ROM was thought of as a database capable of storing 550 megabytes of data that eventually grew to 650 megabytes. While a LaserDisc uses the heat of a laser to literally "burn" a pit, or fuse tracks, into a reflective spot, the CD-R uses a photosensitive dye layer requiring only the light intensity of the laser to create the surface data record.
