Latest Patents

One of his latest patents is titled "Automatic calibration of the output power of a pickup head for an optical information recording apparatus." This invention discloses an automatic calibration method that avoids laser diode thermal effects through duty cycle control. It establishes the correct conversion function between the output current of a front monitor diode and the output power of the pickup head by curve fitting. This method simplifies the calibration process, requiring only one set of measurements for the front monitor diode output current and the pickup head's output power conversion function. The same conversion function can be applied to all pickup heads of the same type, allowing for automatic detection of parameters for optimal recording characteristics.

Another significant patent is "Apparatus and method for analyzing the read-out signal of an optical storage media." This invention is particularly suitable for analyzing high-frequency signals read from digital video disks (DVDs). The apparatus records maximum or minimum values of specific signal periods for further statistical analysis. It processes the AC and DC components of the high-frequency signal independently, combining the results for further processing. This approach requires moderate memory capacity and acquisition time while ensuring accurate results.
