PURPOSE:To improve greatly the quality of a reproduced sound signal and at the same time to attain the after-recording of the sound signal, by recording the sound signal with overlap at the high band side of a video signal by means of a head exclusive for sound. CONSTITUTION:A sound signal 3 is recorded with overlap at the high band side of an FM luminance signal by means of a head exclusive for sound. As a result, the quality can be extremely improved for the record signal in case a metallic tape, etc. having a high band is used for a recording medium. In addition, the S/N, the frequency characteristics, the distortion factor, the wow and flutter, etc. are all extremely improved for the sound signal since the PCM recording is performed at the high band side of a video track. At the same time, the crosstalk produced from an adjacent track can be greatly reduced. Furthermore an after-recording function is attained since the sound signal can be reproduced and then recorded again. |
