とを特徴とする光学式ピツクアツプ。 A movable chassis that moves along the recording surface of the optical disk is provided, a lens holder is movably supported by a shaft on the movable chassis, and a magnetic drive mechanism that drives the lens holder in the rotational direction and the axial direction. In an optical pickup, an optical system is mounted on a movable chassis, the optical system having a light emitting element and a light receiving element for sending and receiving a detection beam to and from an objective lens held in a lens holder. The axis of the actuator is fixed on the movable chassis, and a second support stand supports the lens holder via an elastic support member, and a first support stand supports the magnetism generating member constituting the actuator. An optical pickup characterized in that the optical pickup is configured such that its rotational position about the axis relative to the movable chassis can be adjusted.
