ABSTRACT:
A method of tray ejecting force control for a tray-type optical drive is disclosed. A preliminary input voltage is provided to a DC motor of the tray-type optical drive to perform a preliminary ejection of a tray-type optical drive tray during a preliminary time period. When the preliminary time period is shorter than a predetermined time period, a first voltage smaller than the preliminary input voltage is provided to the DC motor to eject the tray. Alternately, when the preliminary time period is longer than the predetermined time period, a second voltage greater than the first voltage is provided to the DC motor for to eject the tray.
