Latest Patents

One of his latest patents is the "Focus Search Apparatus and Method." This invention provides a focus search apparatus and method for performing a focus search after moving an optical pickup to a focus-on point according to a signal output from a sine wave generator. This technology ensures that a stable and smooth focus search is performed. In this method, a sine wave is generated in response to a focus search command, allowing the optical pickup to be driven in response to the amplitude of the sine wave during the focus search and a filtered focus error signal during a focus servo.

Another significant patent is the "Frequency Detector of Phase Locked Loop." This invention generates a clock signal for reproducing a signal from an optical disc. It compares 3 T information corresponding to the upper limit of the frequency of the Eight-to-Fourteen Modulation signal with the oscillation clock of the VCO divided by three to reduce the oscillation frequency of the VCO. Additionally, it compares 11 T information corresponding to the lower limit of the frequency of the Eight-to-Fourteen Modulation signal with the oscillation clock of the VCO divided by eleven to increase the oscillation frequency of the VCO, thereby providing a VCO that oscillates at a frequency corresponding to the frequency of the Eight-to-Fourteen Modulation signal.
