ABSTRACT:
A system for playing back information recorded on a recording disc including a memory for storing a demodulated signal information. A read out clock signal generator produces a read out clock signal synchronized with a playback clock signal obtained according to information reproduced from the recording disc. The system is further provided with means for monitoring a memory utilization factor of the memory and a control signal is produced according to the result of the monitoring of the memory utilization factor. Thus, an overflow of the demodulated digital data in the memory is prevented.
