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.

When a new CD is needed, the one playing is stopped and pushed back in to the cartridge. The push-rod mechanism moves to the next CD and activates the mechanism to remove the CD from the cartridge. Cartridge CD changers are popular in cars because the cartridges can be easily removed to change CDs.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.
