ABSTRACT:
Method for changing access speed of an optical disk drive, which is used to switch the optical disk drive with different access speeds, to provide the optimal mode for data access. The method places an RC circuit between the electrical circuits and one of the buttons of the disk drive. Pressing the control button varies the input voltage of the control circuit and the control circuit changes the work speed of the optical disk drive motor.
