Latest Patents

Tsuchimochi holds a patent for an optical disk drive designed for precisely adjusting the intensity of laser light irradiated onto an optical disk. The patent describes an amplitude detection circuit that detects the peak value of an output signal from a photo-detector, which is amplified by a head amplifier. This peak value is read into a drive controller and compared with a target value suitable for coding a detected signal in binary format. The gain of a variable gain amplifier is adjusted accordingly, allowing for stable codification of the detected signal. Under the control of the drive controller, a recording power level calculation circuit determines a test writing power level for test writing on a test track of a magneto-optical disk. The circuit then calculates the actual record power for each zone of the disk based on the test writing power level.
