Abstract
A system for positioning a pick-up head of a disk player at a predetermined point having an address determining circuit to determine the position of the pick-up head. A calculating circuit determines the distance to a target position on the basis of the address detected. A controller provides a move output signal to displace the pick-up head at high speed to the target position. The address (location) of the head is again determined and a second move operation performed to plan the pick-up within a predetermined range so that a search for the target address can be performed.
