'''CD-R''' ('''Compact disc-recordable''') is a [[digital media|digital]] [[optical disc]] [[data storage device|storage]] format. A CD-R disc is a [[compact disc]] that can only be [[Write once read many|written once and read arbitrarily many]] times.

CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike [[CD-RW]] discs.
