Optical disc drive

摘要

An optical disc drive adjusts the skew and the misalignment of the rotation centre of an optical disc and a light beam centre of an optical pick-up. The optical disc drive includes an optical pick-up recording/reproduce information onto/from the optical disc (D), pick-up shafts (41) guiding the optical pick-up, an adjusting device (53) moving the pick-up shafts vertically to adjust a slope of the optical pick-up, and shaft guides (51) guiding the pick-up shafts to travel vertically and horizontally. The shaft guides include guide surfaces (51a) contacting the pick-up shafts. The shaft guides guide the pick-up shafts to move towards the turntable when the pick-up shafts move upward, and guide the pick-up shafts to move away from the turntable when the pick-up shafts move downward.
