Abstract
An optical disk drive includes a base for holding an optical disk, a protrusion protruding out from the base that extends through the center hole of the optical disk when holding the optical disk, and at least one hook rotatably installed on the protrusion. When the disk drive stops, the hook is retracted to within the edge of the protrusion and when disk is rotated up to a predetermined speed, the hook extends out from the edge of the protrusion to hook the optical disk.
Claims8
An optical disk drive for driving an optical disk, wherein the optical disk has a center hole, the optical disk drive comprising:
- a base for holding the optical disk;
- a protrusion protruding out from the base for that extends through the center hole when carrying the optical disk;
- and
- at least one hook rotatably installed on the protrusion;
- wherein the hook is a magnetic hook, and the protrusion further comprises a magnet to attract the hook,
- wherein when the disk drive stops, the hook is retracted by the attractive force of the magnet to within the edge of the protrusion and when disk is rotated up to a predetermined speed, the hook extends out from the edge of the protrusion to hook the optical disk.
An optical disk drive for driving an optical disk, wherein the optical disk has a center hole, the optical disk drive comprising:
- a base for holding the optical disk;
- a protrusion protruding out from the base that extends through the center hole of the optical disk when carrying the optical disk, the protrusion comprising a magnet;
- and
- at least one hook slidably installed on the protrusion, wherein the hook is magnetic and is attracted to the magnet of the protrusion,
- wherein when the disk drive stops, the hook is retracted to within the edge of the protrusion and when disk is rotated up to a predetermined speed, the hook extends out from the edge of the protrusion to hook the optical disk.
