摘要： An optical disk apparatus comprises an optical pickup for directing a light beam onto pits formed in an optical disk and for receiving reflected light from the optical disk, an optical pickup supporting member including two guide rods for guiding the optical pickup in a radial direction of the optical disk, two first mounting members for mounting ends of one guide rod, and two second mounting members for mounting ends of the other guide rod, a chassis for mounting the first and second mounting members, an optical pickup driving mechanism including gears and a motor to move the optical pickup in a radial direction of the optical disk, a turntable on which the optical disk is located, and an optical disk drive motor for rotating the turntable. Each of the first fixing members includes a base fixed to the chassis, a guide rod supporting member for fixedly supporting the guide rod, and a flexible member located between the base and the guide rod supporting member for causing the guide rod supporting member to be displaced in a vertical direction with respect to a surface of the optical disk. A natural frequency of a system consisting of the one guide rod, the first mounting member, and the chassis is set to be less than that of the optical pickup, and of the optical disk.
