    摘要： A clock timing extraction circuit for use in an information recording/reproducing apparatus has a phase comparator for comparing the reproduced signal with a selected clock signal to generate a phase error signal, a clock signal generation circuit for adjusting frequency to cause the error signal to approach zero according to the phase error signal and outputting a plurality of clock signals having mutually different phase differences, a selection circuit for outputting one of the plurality of clock signals on the basis of a selection signal, a phase difference judgement circuit for determining one of the plurality of clock signals having a minimum phase error (Vdet) and generating a selection signal for selection of the clock signal having the minimum phase difference, and a freeze circuit for blocking an output of the phase comparator until the clock signal having the minimum phase error is selected. The information recording/reproducing apparatus has an AGC circuit for limiting an amplitude of a reproduced signal received from a recording medium, the aforementioned clock timing extraction circuit, and a decoder circuit. The clock timing extraction circuit extracts a clock signal from an output signal of the AGC circuit and the decoder decodes the output signal of the AGC circuit on the basis of the extracted clock signal.

    摘要： A waveform equivalent circuit for correcting the asymmetry of the rising and falling slopes of an isolated signal waveform retrieved from a magnetic recording medium so as to restore an acute, symmetric isolated waveform. In operation, the input signal is phase-shifted and attenuated, and then added to the input signal to produce a smaller double peaked waveform, which is modified with an inverted and attenuated version of the input waveform. The input signal waveform is subtracted from the modified double peaked signal waveform to diminish both slope sections, and an acute, symmetric original signal waveform is recreated.
