Double-sided recording/reproducing disk drive

A disk drive comprising:

• a main case;
• an intermediate chassis supported by the main case;
• a turn table for rotatably supporting a disk thereon:
• a pickup for recording and/or reproducing data signals on the disk rotatably supported on the turn table;
• and
• a disk transfer mechanism for transferring the disk bidirectionally between a recording and reproducing position, which confronts the turn table, and a disk loading and unloading position at the outside of the disk drive;
• a turning movement mechanism for turning the turn table and the pickup at once from a first position, which confronts one side of the disk, to a second position, which confronts the other side of the disk or vice versa;
• and
• a component base on which at least the turn table and the pickup are mounted, the component base being supported by the main case for turning about a center line that extends through a center of the turn table and a center of the pickup,
• wherein the turning movement mechanism is arranged to turn the component base about the center line so that the turn table and the pickup can be turned between the first position and the second position,
• wherein the intermediate chassis is disposed between the main case and the component base while the turning movement mechanism is arranged for turning the component base in relation to the intermediate chassis.
