In this case, the reproduction by the video head 3 is executed correctly. In the reproduction by the video heads 2 and 5, since the azimuth angle of the video head 2 differs from that of a recorded track, a frequency modulation luminance signal 9 is reproduced by the video head 5 only and a low frequency conversion chrominance signal 8 is reproduced by the video head 2 by utilizing the less azimuth effect conversely. Further, in order to minimize the effect of the low frequency conversion chrominance signal by the video head 5, the head width of the video head 5 is made narrower than that of the video head 2.
