Latest Patents

One of his latest patents is for a near-field objective lens for an optical head. This invention allows for the reading and writing of high-density data on optical discs. The lens is designed to converge an incident beam on a surface coated with a film that produces a surface plasmon effect. This process generates a micro aperture that minimizes the diameter of the light spot, thereby increasing the data capacity stored in the optical disc.

Another significant patent is for an automatic calibration method of the output power of a pickup head for optical information recording apparatuses. This method 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 approach simplifies the calibration process, requiring only one measurement set for optimal recording characteristics.
