Grooves are not formed in the control zone or read-only zone, and read-only data such as control data, audio-video data, or computer data is pre-recorded as a sequence of pre-formed pits on the track center line. The track pitch of the pre-formed pit sequences in the control zone or read-only zone is equal to the groove pitch in the read-write zones.
