ABSTRACT:
N-channel component signals (N.gtoreq.3) of a video signal is recorded and reproduced by N pairs of magnetic heads in any tape speed mode. The N pairs of heads are mounted on a circumference of a rotary cylinder so as to be disposed in the rotating direction of the rotary cylinder at substantially constant intervals of (180/N) degrees with each pair of heads being disposed to be apart by substantially 180 degrees from each other. The relative heights of the heads in each pair in an axial direction of the rotary cylinder are substantially the same. The widths of the N pairs of heads are substantially the same. Signal timings are adjusted by delay circuits before recording and after reproduction.
