Abstract
A disk transport mechanism in a disk drive is connected with a transmission gear mechanism. A loading motor drives the disk transport mechanism. When the loading motor rotates forwards, an optical disk is carried by the disk transport mechanism to a chuck position. When the loading motor rotates backwards, the optical disk is moved back to an ejection position. In failure of the loading motor, an emergency pin is pushed to actuate an emergency disk ejector. A first gear wheel in the transmission gear mechanism is disengaged by the emergency disk ejector to separate the transmission gear mechanism into a disk transport mechanism side and a motor. A second gear wheel on the disk transport mechanism side is rotated to actuate the disk transport mechanism. The emergency pin is pushed repeatedly to cause the disk transport mechanism to move back the optical disk to the ejection position.
