Abstract
A disk player is provided in which clock pulses of a frequency corresponding to the frequency of a synchronizing signal separated from a video signal obtained from the disk is generated and a disk code separated from the video signal is demodulated by the clock pulses, which makes it possible to perform a search operation in a short time.
