ABSTRACT:
An objective lens actuator in which an objective lens for focusing a light beam on a recording medium is held in a lens holder, and the objective lens holder is held on a support shaft to be slidable in a direction of the optical axis of the objective lens and pivotal on a plane perpendicular to the optical axis direction includes a balance weight located on the holder to be substantially axially symmetrical with the objective lens. The balance weight includes a balance weight body having a predetermined mass, and a damper for supporting the balance weight body in the lens holder and for damping a vibration of the lens holder in cooperation with the balance weight body.
