Abstract
A method for controlling the operation of a disk player pickup control system includes the steps of reading position data representing the present position of a pickup from a disk, calculating the distance from the present position to the home position of the pickup according to the position data thus read, and moving the pickup to the home position according to the distance thus calculated. The above-described method for operating the control system is particularly advantageous in that it allows the pickup of a disk player, which does not include a mechanical limit switch, to be moved to the home position.
