Tray controlling method using multiple different voltages
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 and retraction operation, a firmware for receiving signals transmitted by the detect switch upon reaching the different inclined positions so as to adjust a voltage applied to a DC motor and the speed for moving the tray to the different positions such that the tray moves stably when retracting into and ejecting from the disk drive.
