Abstract
A control method for ejecting optical disk from optical disk driver is proposed and applicable to both vertical type and horizontal type optical disk drivers. The control method firstly measures the minimal voltage require by the tray motor to eject a tray with or without an optical disk loaded thereon. Afterward, the disk loading condition of the tray is examined before the ejecting voltage is applied to the tray motor. The minimal voltage determined in above is applied to the tray motor according to the disk loading condition of the tray.
