ABSTRACT:
An apparatus for playing CLV disks is provided with a speed signal generator for generating a speed signal having a frequency corresponding to the rotational speed of the disk, and the rotation of the disk is controlled so that the frequency of the speed signal equals to a predetermined frequency independently of the radial position of an information reading point of a pickup, thereby the period of a search operation of the apparatus is shortened.
