Patent ID: 7418607

Claim:
An automatic power conservation method for an optical media device, comprising the steps of: using a host interface of the optical media device to turn off a plurality of circuit components that are still in operation after the optical media device enters a sleep mode, and when the optical media device is in the sleep mode the host interface being used to respond to an external signal and decoding the external signal utilizing an AUTOACK function; and using the host interface of the optical media device to wake up the plurality of circuit components if the external signal requests the optical media device to leave the sleep mode, wherein, when the external signal sent from the host is not a Sense command signal, the optical media device waking up and exiting the sleep mode, and wherein, when the external signal sent from the host is a Sense command signal, the AUTOACK function is utilized to decode the external signal and the optical media device remaining in the sleep mode.
