PROBLEM TO BE SOLVED: To provide an optical disk device in which tracking servo deviation during recording or regeneration operation is prevented.SOLUTION: A lens shift admissible value adjustment unit 205 performs adjustment to deviate a lens shift occurence admissible range to an inner peripheral side or an outer peripheral side in a radial direction A of an optical disk 4 when a tracking servo deviation detection unit 202 detects tracking servo deviation. By this, the lens shift occurence admissible range can be adjusted in accordance with a movable range of an objective lens 106 deviated to the inner peripheral side or the outer peripheral side in the radial direction A of the optical disk 4, and tracking servo deviation during recording or regeneration operation can be prevented. |
