Abstract

PURPOSE:To control the reproduction of the inner and outer circumferences of a constant linear velocity (CLV) optical disk with an identical servo characteristic by detecting the position of a pickup and controlling a gain control circuit. CONSTITUTION:The position of a pickup 1 to slide a shaft 41 is detected by switches 35-39 of a position detecting device 31, according to a detected position, the output in response to the feedback control signal of a driving circuit 17 for a disk motor 19 is controlled through a gain control circuit 33. Thus, the reproduction of the inner circumference and the outer circumference of the CLV optical disk can be controlled with the identical servo characteristic, and the optimum design of a CLV servo circuit can be simplified.
