Title: Tracking control circuit
Inventor: TSUKADA KAZUYA
IPC: G11B7/095
Filed: 1990-04-27
Abstract: PURPOSE:To obtain a measured result without being affected by eccentricity by measuring the eccentric amount of an optical disk, storing it as an eccentric signal and moving a light beam based on a groove cross signal for moving the read-out eccentricity signal and the light beam radially. CONSTITUTION:A position signal detected by a light beam position sensor 11 is inputted as an eccentricity signal H to a processing circuit 13 since the position of the light beam is controlled to a specified track, and a component for one rotation of an optical disk is stored. An adder 16 adds the eccentricity signal H read out from the circuit 13 and a groove cross signal S set to prescribed inclination and they are inputted through a switch 8 and an amplifier 9 to a tracking actuator 10. Based on these signals H and S, the actuator 10 moves the light beam. Thus, the position of the light beam is controlled while following up the eccentricity, and the number of tracks to be crossed can be fixed. Then, the measured result can be obtained without being affected by the eccentricity.
