摘要:
An optical disc device is provided with an optical pickup (6), which has a light source (23) which emits an optical beam (21) for irradiating an optical disc (100), at least one objective lens (22) for focusing the optical beam (21), and an actuator which shifts the objective lens (22) in a direction vertical to the optical disc (100); a transfer table (11) for transferring the optical pickup (6) in a disc diameter direction; a rim detecting means (30) for detecting that an irradiation position of the optical beam (21) is over an edge section of the optical disc (100), in the case of shifting the optical pickup (6) from an inner circumference side to an outer circumference side of the disc for seek operation; and a control means (40) which shifts the objective lens (22) in a direction to be away from the optical disc (100) by the actuator when the irradiation position of the optical beam (21) is detected over the edge section of the optical disc (100), and shifts the optical pickup (6) to the disc inner circumference side by the transfer table (11).
