    Abstract: A limit switch controlling method and apparatus used in an optical drive are disclosed. When the optical drive is executing a tray-in/tray-out action or a move-sled home action, a detect-tray-in-switch pin, a detect-tray-out-switch pin, or a detect-sled-limit-switch pin of a controlling chip is used to receive a signal from a limit switch. When the optical drive is not executing the tray-in/tray-out action or the move-sled-home action, the detect-tray-in-switch pin, the-detect tray-out-switch pin, or the detect-sled-limit-switch pin of the controlling chip is used as an I/O port.
