Optical pickup device

摘要

A skew of an optical pickup device can be adjusted by a movable-side member itself which holds thereon an objective lens. A holder (33) which holds an objective lens (32) is supported by four spring wires (43) such that it can be moved in the focusing direction and the tracking direction of an optical disk. A center of a magnetic circuit (M) which drives the holder (33) is shifted in the outer peripheral side relative to the optical disk. Elastic force of the spring wires of the inner peripheral side is suppressed by increasing the amount of a gel material (72) bonded to the spring wires located on the inner peripheral side of the optical disk as a damping material as compared with the amount of the gel material (72) bonded to the spring wires located on the outer peripheral side. Thus, the holder (33) can be driven by a predetermined inclination in the focusing direction such that the optical axis of the objective lens becomes substantially perpendicular to the signal recording surface of the optical disk in response to the focus height changed due to the skew of the optical disk. <IMAGE>
