ABSTRACT:
An information recorded disk player designed in such a way that spindle servo control is executed on the basis of a sync signal in a video signal while a reading clock for reading memory in a digital demodulation system is synchronized with a reproduced clock, and the low frequency component of a time base error signal is removed from a signal representing the phase difference between these clocks, thereby eliminating the eccentric component and improving the tone quality.
