ABSTRACT:
A compact-disc-digital-audio player may be adapted to read optical audio discs in which digital information is stored by controlling the time-base correction circuit in this player by means of a clock signal whose frequency is not a constant reference frequency but a frequency which is locked to the time base of the signal being read. As a result of this both the data signal and the subcode will have the same time base without the necessity of modifying the integrate circuits available for the compact-disc digital-audio player.
