| 摘要 |
The present invention with an optical disk drive controller and an optical pickup head connected together by a flexible cable is described. The device includes a delay adjusting module located within the first module for delaying a first signal by an amount specified by a calibration signal. The first module transmits the delayed first signal and a second signal through a first signal channel and a second signal channel, respectively, to the second module of the optical pickup head, a monitoring module located within the optical pickup head for receiving and reshaping the delayed first signal and the second signal so as to generate a monitor signal. A calibration signal-generating module is located within the optical disk drive controller for receiving the monitor signal so as to generate the calibration signal.
