Abstract: The disclosure discloses a compensation method in a radial direction on a label side of an optical disc. An optical disc is inserted into an optical disk drive. The data side of the optical disc is divided into at least one compensation area. An optical pick-up head (OPU) is moved from inner to outer rings by simulating a writing process. The OPU is moved to some pre-determined points and radial-directional compensation is performed to obtain radial-directional voltage gains at the pre-determined points. The voltage gains are recorded. The label side of an optical disc is inserted into the optical disk drive. The simulated track number is calculated on the basis of the required moving distance for the OPU to write pattern on the label side. The OPU is moved to write the label side by a radial-directional lens driving voltage compensated with a gain obtained from a compensation formula.

Abstract: A method for calibrating signal offsets on a lightscribe disc is provided. Spoke signals of an inner ring are utilized as a counter in order to read information pattern signals of an outer ring in a predetermined marked area. Measure the signal offsets of the information pattern signals. Check whether the number of the spoke signals of the inner ring exceeds a predetermined value. When the number of the spoke signals does not exceed the predetermined value, continue to measure the signal offsets; and when the number of the spoke signals reaches the predetermined value, calculate an average signal offset. The signal offsets of the information pattern signals of the outer ring can be calibrated by utilizing the average signal offset during a radial calibration or a decoding calibration.
