Abstract
An optical disk apparatus includes a carriage, an actuator for performing focus and tracking control, a first lens supported by the actuator, and a suspension member mounted on the carriage. The optical disk apparatus also includes a slider attached to the suspension member to be brought into facing relation to a storage disk. A second lens is supported by the slider to be associated with the first lens. The optical disk apparatus further includes optical axis adjusting means separate from the actuator. The adjusting means is designed to move the first and the second lenses to each other in parallel to the disk member.
Claims14
An optical disk apparatus comprising:
- a carriage movable relative to a data-storing disk member;
- an actuator mounted on the carriage and movable at least for performing focus control;
- a first lens supported by the actuator and having a first optical axis;
- an elastically deformable suspension member provided with a first end and a second end, the suspension member being supported by the carriage via the first end;
- a slider attached to the second end of the suspension member and brought into facing relation to the disk member;
- a second lens supported by the slider and having a second optical axis, the second lens being associated with the first lens to make a light spot on the disk member;
- and
- an optical axis adjuster provided separately from the actuator and arranged to move the first and the second optical axes relative to each other in predetermined direction parallel to the disk member;
- wherein the optical adjuster comprises a shifting mechanism which causes the carriage and the disk member to be moved toward and away from each other for elastically deforming the suspension member to move the first and the second optical axes relative to each other in said predetermined direction.
