CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format. A CD-RW disc is a compact disc that can be written, read arbitrarily many times, erased and written again.The technology was introduced in 1997.CD-RW discs (CD-RWs) require readers that have more sensitive laser optics than plain CDs.Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW. CD-ROM drives that bear a MultiRead certification claim compatibility.CD-RW discs need to be blanked before reuse.D-RW discs (CD-RWs) require readers that have more sensitive laser optics than plain CDs.

Cartridge Changers. Cartridge CD changers are often found in cars. In a cartridge CD changer, between six and twelve CDs are slipped into a cartridge. The cartridge is then inserted into a CD changer. A rod in the CD changer moves to the desired CD and slides into the cartridge activating a mechanism inside the cartridge.The mechanism moves a CD to the player mechanism where it is aligned with the center spindle and laser reader.n these changers, the CD player mechanism is also vertical. When the desired CD is played, an arm rolls the CD into a mechanism that holds the CD. The CD drive assembly clamps the CD to a spindle that passes through the hole in the CD.
