PROBLEM TO BE SOLVED: To prevent cross-talk from occurring and tilt servo operation from causing a disturbance of other servo, and to perform stable servo operation by suppressing a tilt error within a mechanically allowable range, in an optical disk device in which all of focus servo, tracking servo, radial tilt servo, and tangential tilt servo are performed. SOLUTION: An optical disk device 100 is provided with an actuator 110 performing focusing operation of an optical pickup 111, tracking operation, and tilt operation of one direction, and a tilt adjusting mechanism 120 performing tilt adjustment of the other direction. The tilt adjusting mechanism 120 has an actuator supporting part 130 supporting an actuator 110, and a tilt correcting part 140 performing tilt correction in which a tilt angle formed by a recording plane of an optical disk 5 and a lens plane of the optical pickup 111 is adjusted by rotating an actuator supporting part 130 around a straight line in the radial direction.
