Claims

[Scope of Claim for Utility Model Registration] A U-shaped rail having a U-shape with an upper parallel portion facing the upper surface of the disk and a lower parallel portion facing the lower surface of the disk, and a rack formed on the outer peripheral surface of the U-shape, and a light. Attached to a fixed shaft fixed to the head,
a reference roller that is guided in contact with the inner circumferential surface of the U-shaped rail;
a tilt drive roller that is guided in contact with the inner circumferential surface of the shaped rail; a tilt drive device that is attached to the optical head and drives the tilt drive roller up and down; and the reference roller and the tilt drive that are attached to the optical head. a feed gear that is attached to be elastically movable up and down so as to sandwich the U-shaped rail between rollers, and that engages with a rack on the outer peripheral surface of the U-shaped rail; and a feed drive device that rotationally drives the feed gear. An optical disk device featuring the following features.
