    Abstract: A layer-jumping control device and method for an optical disc device includes a calculator, a controller, and a driver. The calculator is configured to receive an error-focusing signal, and to determine a peak and a trough of the error-focusing signal. The controller, coupled to the calculator, is configured to process the error-focusing signal to generate a control-focusing signal. The driver, coupled to the controller, is configured to convert the control-focusing signal to a control-driving signal. The device further includes a counter coupled to the calculator, and enables the layer jump when the counter reaches a predetermined value.

    Abstract: An optical disc drive generates a control signal according to the delay of a TZC signal. The control signal can determine if an optical pickup of the optical disc drive crosses a track. When the optical pickup is reading a defective section of an optical disk, the optical disc drive cannot correct the movement of the optical pickup. Therefore, after the optical pickup passes through the defective section of the optical disc, the optical disc drive adjusts the gain of the tracking drive signal according to the control signal.
