Abstract
A mass-manufactured disc containing audio and non-audio data, the audio portion of which can be satisfactorily played by an audio-only player without playing the non-audio portion. The disc is mass-manufactured from a patterned glassmaster by either (1) generating suitable multisession-formatted data and subcode information and writing this data onto the glassmaster, or (2) reading data stored on a write-once multisession disc and writing this data directly onto the glassmaster.
