ABSTRACT:
An optical disk drive according to the present invention includes, a drive base (10); a traverse base (20) having a turntable (5), a first motor (3) for turntable drive, an optical pickup (6) and a drive mechanism thereof; and an intermediate base (80) disposed between the two bases, so as to swing vertically relative to the drive base and support the traverse base through an elastic body. A drive power transfer path switching mechanism is provided for switching the path through which drive power from a second motor4can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism, so as to make it possible to perform a disk loading operation, a disk rotating operation and a pickup driving operation by 2 motors, and to make it possible to achieve both absorbing vibration from outside and suppressing vibration generated by the rotating operation of the turntable.
