Abstract
A controlling method of an optical disc drive includes the following steps. After an optical disc is loaded into the optical disc drive, a start-up procedure is performed to acquire a disc parameter and a disc information of the optical disc. Then, the optical disc drive enters a ready state. If a command from the computer system is received within a predetermined time interval, the command is executed and the optical disc drive enters the ready state again. If no command is received within the predetermined time interval, the optical disc drive enters an idle state corresponding to the presence of the optical disc. Then, the disc parameter, the disc information and a power index tag are written into a non-volatile memory, and a power-interruptible event is issued to the computer system.
