Title: Tracking servo device for optical disk
Inventor: WACHI SHIGEAKI
IPC: G11B7/09
Filed: 1987-06-09
Abstract: PURPOSE:To stably operate a fixed push-pull type tracking servo circuit by impressing the output of an objective value compensator to an actuator model circuit and feeding back the impressed signal. CONSTITUTION:A 2nd feedback circuit is constituted so that a detected tracking error signal is inputted to an actuator model circuit 27 indicating the mechanical transmission characteristics of a tracking actuator 26 through the objective value compensating circuit 22 having peak gain at an eccentric frequency component of a disk, a signal outputted from the circuit 27 is converted into a prescribed level and the level-converted signal is subtracted from the tracking error signal. Since an error signal component outputted at the tine of detecting the movement of the actuator 26 by the push-pull system is removed from a tracking servo loop, accurate tracking servo can be attained.
