Abstract:
A tray control method for a disk drive including a tray for carrying a disk, a detect switch movable to different inclined positions for detecting different positions of the tray during tray ejection operation, a firmware for receiving signals transmitted by the detect switch upon reaching the different inclined positions. The voltage applied to the DC motor for moving the tray is lowered after receiving the first signal for a specific time.
