Red Book 
The informal name for the document released by Sony and Philips in 1980 that defines standards for the audio CD format (then called CD-DA). The Red Book describes the physical parameters for the disc, as well as the number of tracks on the disc that contain digital audio data and the error correction routines that save sound from minor data loss. The format allows for a total of 74 minutes of digital sound to be transferred at a rate of 150 kilobytes per second.
