CD/R

Acronym for Compact Disc Recordable, a blank compact disc that can be recorded onto one time. You can use either a computer CD recorder for data and music, or a dedicated audio CD recorder to make CD copies or record music only. A CD/R can be recorded in one or more sessions, but cannot be played in an audio player until it is closed, after which it can no longer accept data. Maximum storage time is typically 80 minutes or 750 mb with some 99 minute CD/Rs available.
