PURPOSE:To reduce the tilt of the optical axis of an optical pickup when the external force is applied by having a difference in space between connection parts of terminals and the space between the connection parts of an optical pickup. CONSTITUTION:A connection part 3a is provided between a terminal 4 and a support arm 2a; and a connection part 3b is provided between the terminal 4 and a support arm 2b respectively. The space between the parts 3a and 3b is set different from the space between the connection parts 5a and 5b. Thus an optical pickup 1 can follow the surface tilt of a disk 9 with higher fidelity. Now it is supposed that the disk 9 is revolving horizontally. Thus the pickup 1 is moved down with a downward shift of the disk 9, and at the same time the optical axis of the pickup 1 follows the normal line on the disk 9. While the pickup 1 is moved up with an upward shift of the disk 9, and the optical axis of the pickup 1 can follow said normal line. Such effects are obtained. |
