What is the full form of "CD-RW"?

CD-RW is a digital optical disc storage format introduced in 1997. A CD-RW compact disc can be written, read, erased, and re-written. CD-RWs, as opposed to CDs, require specialized readers that have sensitive laser optics. Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW.
