ABSTRACT:
A disk player and a method for operating a disk player in which the picture scanning speed for both a constant angular velocity disk and a constant linear velocity disk are made constant and independent of the characteristics of the slider which carries the pickup or of the radial position of the pickup relative the inner radius of the disk. During a jump operation, the number of tracks detected by a track counter is compared with a designated value, and the jump operation is repeated if a scanning command is still present at the end of the previous operation. In the case of a constant angular velocity disk, the designated value is a fixed value, whereas the designated value is calculated in accordance with the present position of the pickup for a constant linear velocity disk.
