<p>An apparatus for recording and reproducing a video signal and an audio signal (which are recorded in different areas or portions of each slant track on a tape) includes first and second rotary heads (H 1, H2) for recording and reproducing the video and audio signals in alternate tracks, and a playback circuit (2, 3, 4) for processing luminance and chrominance components of the video signal reproduced by the first and second rotary heads (H1, H2) when scanning video signal-containing areas of the respective tracks. The apparatus also includes a circuit (20) for supplying a new audio signal from an input terminal (19) to the rotary heads (H1, H2) for recording, a signal generator (7) for generating a predetermined signal to be substituted for the processed luminance component, and a muting circuit (15) for muting the reproduced chrominance component. The predetermined signal from the signal generator (7) is substituted for the processed luminance component, and the chrominance component is muted by the muting circuit (15) during recording of the audio signal in place of a previously recorded audio signal, thereby suppressing noise bars which might otherwise appear in the reproduced picture.</p> |
