Abstract
A compact disk player for playing back data recorded on a compact disk. The compact disk has a surface on which a lead-in area, a program area and a lead-out area are distinctly provided. The program area contains data to be played back to which an address is allocated. The compact disk player includes a pickup and a servo mechanism for controlling the position of the pickup. The compact disk player further includes a controller for servo-locking the pickup to a position where the reading of the data contained in the program area is interrupted and controlling the servo mechanism so that the pickup is positioned in a predetermined position allocated with a predetermined address for the sake of subsequent resumption of the data reading if an address of the servo-locked position is outside the program area.
