摘要： 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.

摘要： A method for calibrating a focusing error signal of a lightscribe disc includes the following steps. An optical pickup head is moved to a focusing reference surface by utilizing radial voltages to some predetermined measuring positions to find and record the best gain value used to calibrate the asymmetry of the focusing error signal. The best gain fitting curve is formed by curve-fitting, based on the recorded radial voltages and the best gain values. The best gain value is obtained by an interpolation or extrapolation method, and used to calibrate the asymmetry of the focusing error signal of a lightscribe disc.

摘要： 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.

摘要： A method and an apparatus for capturing encoded signals on a label surface. A pick-up head is utilized to detect all or predetermined codes on a control feature zone of a label surface of a Light Scribe disc so as to generate a sub-beam added signal. A calculation unit is used to calculate the average value of the sub-beam added signals. A dynamic slicer, which could dynamically set its standard value at a half of the average value of the sub-beam added signals, slices the sub-beam added signals and captures the encoded signals. A processor decodes the encoded signals and translates those into Light Scribe disc's information.

摘要： An apparatus and a method for testing spoke sensor are disclosed. A drive unit is started to rotate a test disc to a predetermined rotation speed. A module test unit is electrically connected to a spoke sensor under test of a spindle motor module. The module test unit is started to drive the spoke sensor to detect the spoke signals of the test disc and record the number of detected spoke signals. Within a test time, a comparison unit is used for comparing the number of spoke signals with a threshold, and only when the detected number is larger than a threshold will the spoke sensor be assembled to the product. Thus, the product quality is assured.
