ABSTRACT:
Apparatus for reproducing digital video signals from a magnetic tape, wherein a frame of digital video signals had been recorded in 2 m tracks (m is an integer greater than 1), in which a pair of rotary heads having respectively different azimuth angles scan traces across the magnetic tape, such traces substantially coinciding with the tracks when the magnetic tape is transported at a speed equal to the recording speed. The magnetic tape is transported at a high speed equal to (m.times.n.+-.l) times the recording speed, where n is an integer greater than 0, l=0.5 when the pair of heads are arranged as a double azimuth head assembly and l=0.25 when the heads are angularly separated by 180.degree..
