み出しを開始する情報記録再生装置。 It consists of a device that reads out a signal stored in a memory input at high speed at a slower speed than the stored speed, and a device that compares the waveform of the output signal of the device with the waveform of the high speed input signal. An information recording and reproducing device that, when increasing trends of waveforms match for a certain period of time, stops reading the earlier stored part of the memory from then on and starts reading from the later stored matched part.
