ABSTRACT:
In a case where tracking control is carried out by a lens actuator in performing a tracking pull-in operation in which tracking control is started in the state where tracking control is out of operation, the tracking control circuit brings control into stable tracking control by moving the light spot onto a groove on the optical disc. After that, when tracking onto a land is needed, the tracking control circuit moves the light spot onto the land. This enables a pull-in action toward a stable tracking operation.
