PROBLEM TO BE SOLVED: To provide a control device for tilting of an optical pickup whose manufacturing cost is reduced by simplifying the structure for arranging the optical pickup in parallel to a disk plane and whose tracking characteristic of tilt control is improved by lightening the driven part. SOLUTION: One end part 4a of a sliding shaft 4 journaling an optical pickup 3 freely slidably is held by a holding member 14, the other end part of the sliding shaft 4 is supported by a shaft parallelism adjusting member 13 having elasticity. The sliding shaft 4 is tilted by the operation of a drive member 15 oscillatably driving the holding member 14 and the tilt of the optical pickup is controlled. Since the other end part 4b is held by the shaft parallelism adjusting member 13 freely tiltably, the sliding shaft 4 can be tilted tracking the oscillation of the holding member 14, and the tilt control of the optical pickup is performed appropriately. Thus, the structure of the device is simplified, also, the holding member 14 being a driven part can be lightened. COPYRIGHT: (C)2004,JPO
