Claims24
A disk drive comprising:
- a main chassis;
- a tray that is configured to have a disk removably mounted thereon and that is installed to slide into/out of the main chassis, the tray comprising a pickup transporting unit that is configured to move a pickup base back and forth in a radial direction of the disk;
- and
- a lock releasing unit which is arranged on the tray, is driven by the pickup transporting unit, and releases a lock of the tray from the main chassis,
- wherein the lock releasing unit comprises a lock lever unit which is rotatably installed on the tray, a link unit which is rotatably installed on the tray, and a connecting unit which is rotatably installed on the tray and connects the lock releasing unit and the lock lever unit.
A disk drive comprising:
- a main chassis;
- a tray that is configured to have a disk removably mounted thereon and that is installed to slide into/out of the main chassis, the tray comprising a pickup transporting unit that comprises a lead screw and a step motor that is configured to rotate the lead screw and to move a pickup base back and forth in a radial direction of the disk;
- and
- a lock releasing unit that is arranged on the tray, that is configured so as to not release a lock of the tray in response to the lock releasing unit being initially combined with the lead screw by the pickup base, and that is configured to release the lock of the tray from the main chassis in response to the lock releasing unit being combined with the lead screw and the lock releasing unit being driven by the lead screw.
A method of releasing lock of a tray from a main chassis:
- by using a lock releasing unit which comprises a lock lever unit which is rotatably installed on the tray and which comprises a hook that is to be combined with a locking protrusion arranged on the main chassis;
- a link unit that is rotatably installed on the tray and comprises a driving force transmitting unit, wherein the driving force transmitting unit is combined with the pickup transporting unit and receives a rotation force, and an interfering unit that is configured to be moved based on contact with a feeding guide that connects the pickup base to the pickup transporting unit;
- and a connecting unit that is rotatably installed on the tray, is connected to the lock lever unit and the link unit, and rotates the lock lever unit by using a rotation force of the link unit, the method comprising:
- combining the lock releasing unit with the pickup transporting unit;
- releasing a lock of the tray from the main chassis;
- and
- returning the lock releasing unit to the initial position thereof.
