Latest Patents

Junko Onaka holds 1 patent for her innovative invention titled "Disk reproducing apparatus for precisely determining a value of an address signal reproduced from the disk." This patent describes a disk reproducing apparatus that includes a variable gain amplifier (VCA). The VCA applies a radial push-pull signal that includes an address signal and an FCM leakage-in signal to a switch. The switch outputs only the address signal to a peak-hold circuit based on an FCM mask signal from a mask signal generation circuit. The peak-hold circuit generates a peak-hold signal of the address signal, which is then output to a DSP. The DSP controls the gain of the VCA based on the peak-hold signal, allowing for precise detection of the address signal.
