ABSTRACT:
A tilting mechanism for the optical pickup unit of an optical information record/playback apparatus such as a video disk player. The optical pickup and a support member for slidably supporting the pickup are tilted together by a tilting servocontrol. The tilting mechanism includes a movable fulcrum about which the optical pickup and the support member are tilted. The fulcrum is moved depending on the position of the optical pickup or on a focusing error signal, so that the tilting servo-control is performed when the fulcrum is in an appropriate position with respect to the distance between the pickup and the disk.
