Abstract

PURPOSE:To ensure the high-accuracy and assured detection of the peak position with no deterioration of the SN ratio with emphasis at the high band like in case the reproduced output waveform is differentiated even though the reproduced output waveform may have some fluctuation. CONSTITUTION:Signal SI showing the peak at the inversion point of the record signal is obtained through reproducing head 1 and then undergoes shaping 2 based on the average level to be turned signal SD. Thus, signal SIP and SPH featuring the waveform along signal SI with nearly the same level are obtained at the emitters of transistor Tr13 and 14 while SI exceeds the average level and reaches the positive peak. If resistance 19 is selected properly, SIP=SPH is satisfied at the peak value. And when the peak is exceeded, Tr14 is cut off to turn SIP<SPH constant. Accordingly, output SPD of comparator 11 is inverted to 1, and the positive peak position of SI can be detected. When signal SI becomes less than the average level, signal SD becomes 1, and capacity 16 discharges through Tr17. Thus, signal SPH lowers down to SIP, and rectangular wave SPD is delivered from comparator 11. Comparator 21 has the symmetrical action, obtaining signal SP equal to signal SR via FF3.
