ABSTRACT:
A disk player in which the audio signal can be reproduced during FAST and SLOW playing modes. The speed of the spindle motor is controlled in accordance with the phase and frequency difference between a reference synchronizing signal and a synchronizing signal derived from information read from the disk. The frequency of the reference synchronizing signal is made variable to vary the speed of the spindle and hence the speed of reproduction of the disk.
