Patent ID: 7616530

Claim:
A method for changing access speed of an optical disk drive having a first input port of a control circuit for changing the access speed of a motor and any button of the optical disk drive being coupled with a RC circuit, by controlling the button to change the potential of the first input port, to drive the motor to change the access speed of the optical disk drive, comprising the following steps: (a) pressing the button continuously; (b) reducing the potential of the first input port by discharge of the RC circuit; and (c) changing the access speed of the optical disk drive when the control circuit detects the potential of the first input port is lower than a preset potential, wherein the button is selected from the group consisting of play, pause, fast forward, and rewind, wherein the first input port is coupled with an input port of another button of the optical disk drive panel, and the another button is connected to the second input port of the control circuit.
