This paper describes a tracking servo system, with a new optical head, capable of locking an objective lens in place in the head. Using the new optical head, the lens position deviation from the center position in the lens movable range can be detected. Head and lens positions are controlled co-operatively using a detected lens deviation signal. In the tracking servo system, no lens vibration ocuurs, disk eccentricity does not cause track offset and track jump can be repeated as many time as necessary. As a result, stable and high speed accessing and accurate track following are achieved.
