Latest Patents
Toshiko Otomo holds a patent for a signal processing circuit designed to detect a tracking error for an optical disk. This invention focuses on detecting a sine wave tracking error signal when an optical spot moves along the radius of the optical disk. The circuit also processes a sine wave whole reflection light quantity signal, which has a phase offset of 90 degrees relative to the tracking error signal. The result is a deformed signal that provides states of 'H' and 'L' at specific timing when the whole reflection light quantity signal crosses the center level of its amplitude.
