Abstract
A control method of an optical disc drive includes steps of: detecting data transmission is being performed between the computer system and the optical disc drive or not; stopping supplying an operating voltage to the optical disc drive if data transmission not being performed; determining whether or not an eject switch is being pressed according to a variation in potential on a shared line when a first logic level is detected, and supplying the operating voltage to the optical disc drive if a press on the eject switch is detected and after a predetermined time ejecting a tray from the optical disc drive; and determining whether or not the tray is loaded into the optical disc drive according to a variation in potential on the shared line when a second logic level is detected, and supplying the operating voltage to the optical disc drive if the tray is loaded.
