Latest Patents

Tsuji Masaaki holds a patent for a "Method and apparatus for optical disk recording capable of reducing settling time and generating an accurate channel clock signal." This invention includes a sophisticated optical disk recording apparatus that features a first comparator, a second comparator, a third comparator, a selection circuit, a control voltage generator, a voltage control oscillator, and a control circuit. The first comparator is responsible for comparing frequency-divided signals to output an error signal. The second and third comparators compare a signal pre-recorded on an optical disk with the frequency-divided signal to produce an error signal and a frequency differential signal. The selection circuit then selects one of the error signals to output. The control voltage generator creates a control voltage based on the selected signal, while the voltage control oscillator generates a write reference clock signal that corresponds to the control voltage. The control circuit manages the operations of the selection circuit according to the frequency differential signals. Tsuji Masaaki's patent is a testament to his innovative approach in this technical field.
