Abstract

본 발명은 더블데크 브이씨알(VCR)에 관한 것으로서, 특히 오디오신호가 하이파이로 녹음된 테이프의 복사시 자동적으로 하이파이모드를 선택하고, AFM된 신호를 직접 녹음하도록 하여 음질이 향상되도록 한 더블데크 VCR의 하이파이오디오신호 녹음회로에 관한 것이다. 즉, 본 발명에 따른 더블데크 VCR의 하이파이오디오신호 녹음회로는, 더블데크 VCR에서 복사하고자 하는 테이프가 하이파이로 녹화된 테이프인 경우에는 자동적으로 하이파이 방식으로 모드로 절환되어 녹음할 수 있도록 한 것이다. 또한, 하이파이로 녹화된 테이프를 복사하고자 할때 재생된 AFM신호를 복조하지 않고 직접 녹음용 하이파이헤드로 녹음하여 신호의 S/N를 향상시킨 것이다.The present invention relates to a double-deck VCR (VCR), in particular, when the audio signal is copied to a high-fidelity tape automatically selects the hi-fi mode, and to directly record the AFM signal to improve the sound quality double deck VCR Relates to a hi-fi audio signal recording circuit. That is, the hi-fi audio signal recording circuit of the double-deck VCR according to the present invention, when the tape to be copied in the double-deck VCR is a high-fidelity tape is to be automatically switched to the mode to record in the hi-fi method. In addition, when copying a tape recorded with hi-fi, the S-N of the signal is improved by directly recording with a hi-fi head for recording without demodulating the reproduced AFM signal.
