ダ。 A luminance signal processing circuit that processes a luminance signal of a video signal, a color signal processing circuit that processes a color signal of the video signal, and video recording that combines and amplifies the outputs of the luminance signal processing circuit and the color signal processing circuit. an amplifier, an audio signal processing circuit for processing a first audio signal accompanying the video signal, an audio rotary head for recording an FM modulated signal of the second audio signal on an FM audio track of a videotape, and the video recording a video rotary head for recording the output of the amplifier on the video track of the videotape; a full-width erasing head for erasing information over the entire width of the videotape; and an output of the audio signal processing circuit for recording the output of the audio signal processing circuit on the audio track of the videotape. fixed audio head;
an audio erasing head for erasing information on the audio track; a control head for reproducing information on the control track of the video tape; and servo control of the video rotating head and the running system of the video tape by the output of the control head. In the high-fidelity video tape recorder, the erasing operation of the video signal and the first audio signal recorded on the video tape by the full-width erasing head is stopped, and the audio rotary head erases the FM signal. A high-fidelity videotape recorder comprising means for recording a modulated signal on said FM audio track.
