소망의2치 부호의 디지탈신호를 변환기 및 지연기를 각기 통하여 해당 변환기에 귀환하고 해당 변환기에 있어서 그를법으로하는 가산에 의해 얻어진 기록용 2치 부호신호를 멀티트랙 기록용 자기 헤드의 대응하는 헤드캡에 공급하여 기록된 멀티트랙이 있는 자기 기록 매체의 해당 멀티트랙을, 멀티트랙 재생용 자기 헤드의 각 헤드캡에 의해 각기별로 재생하는 자기 재생장치에 있어서 상기 멀티트랙 재생용 자기 헤드의-의 헤드캡에 의해-의 트랙의 기기록2치 부호신호를 재생하여 얻은 3치 부호신호가 공급되어 해당 재생 3치 부호신호중의 인접트랙으로부터의 크로스톡 성분을 해당인접 트랙의 재생신호와 거의 상쇄하여 억압하는 크로스톡 켠셀러회로와 해당 크로스톡 켠셀러회로의 출력 3치 부호신호의 파형등화를 하는 등화기와, 해당 등화기의 출력 3치 부호 신호에서 그 +1 및 -1에 상당하는 신호 레벨의 거이 피크치에서 샘플링 펄스를 발생하는 수단과 해당 등화기의 출력 3치 부호신호의 양파정류 출력파형을 해당샘플링 펄스로 샘플링하여 그것을 홀딩하는 샘플홀드회로와, 해당 샘플홀드회로의 출력 참조신호와 해당참조 신호의 시간 맞춤을 위해 지연된 해당 등화기의 출력 2치 부호신호를 각기 레벨 비교하고 상기 기록 2치 부호신호와 동일파형의 2치 부호신호를 출력하는 레벨 비교회로 수단에 의해 이뤄지는 회로가, 해당 각 해드캡 마다에 각기 설치된 것을 특징으로 하는 자기 재생 장치.The digital signal of the desired binary code is returned to the corresponding converter through the transducer and the retarder respectively, and the recording binary code signal obtained by the addition in the transducer is applied to the corresponding head cap of the multitrack recording magnetic head. A magnetic reproducing apparatus for reproducing a corresponding multitrack of a magnetic recording medium having a multitrack recorded by supplying it to a respective head cap of a multitrack reproducing magnetic head for each head of the multitrack reproducing magnetic head. The cap is supplied with a three-value code signal obtained by reproducing the device lock binary code signal of a track, and the crosstalk component from adjacent tracks of the reproduced three-value code signal is almost canceled by the reproduction signal of the corresponding track to suppress it. An equalizer for performing waveform equalization of the output 3-value code signal of the crosstalk-on-seller circuit and the corresponding crosstalk-on-seller circuit, and Means for generating a sampling pulse at the peak of the signal level corresponding to +1 and -1 in the output tri-level code signal and the onion rectified output waveform of the output tri-level code signal of the equalizer with the corresponding sampling pulse. A level comparison between the holding sample holding circuit, the output binary signal of the corresponding sample holding circuit and the output binary code signal of the corresponding equalizer delayed for time alignment of the reference signal is performed, and the two waveforms having the same waveform as the recording binary code signal are respectively compared. And a circuit formed by a level comparison circuit means for outputting a value code signal, respectively provided for each head cap. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
