Abstract
A protection method for manual ejection operation of optical disk driver is proposed. The method sets the tray of the optical disk driver to a locked state when the optical disk driver is in normal rotation. The state of a load-sensing switch is on when the tray is in state of disk loading. When a manual ejection is triggered, the state of a load-sensing switch is off and a controller senses the off state. The controller applies a voltage to the tray motor and change the state of the load-sensing switch to on state. Therefore, the tray of an optical disk driver is set to a locked state.
Claims2
A protection method for manual ejection operation of optical disk driver;
- the method setting the tray of the optical disk driver to a locked state when the optical disk driver is in normal rotation;
- the method having following steps:
- (a) a controller sensing the state of a load-sensing switch of the optical disk driver;
- the state being on when the optical disk is loaded and off when the optical disk is not loaded;
- (b) the state of a load-sensing switch being changed to off state when a manual ejection operation of the optical disk driver is activated;
- (c) the controller sensing the off state of the load-sensing switch and applied a disk-loading voltage to a tray motor of the optical disk driver;
- the state of a load-sensing switch being changed to on state from off state and the tray of an optical disk driver being set to a locked state.
