ABSTRACT:
In a helical scan type magnetic tape recording apparatus, one thin film multi-recording head is mounted on a rotary drum, wherein the multi-recording head includes N recording heads for recording N recording tracks at a predetermined track angle on a magnetic tape by one rotation of the rotary drum to perform recording for forming continuous recording tracks having the same track pitches, by determining rotary drum rotation and a tape speed in accordance with equation V1=Tp·N·(RPS)/sin θ, such that (N−1) recording tracks having the same track pitches narrower than the head width and one recording track having a wider track width than that are formed by a first rotation of the drum, then by a second rotation, a preceding recording head overwrites the recording track having the wider track width to form a recording track having a track width equal to the track width of the recording track.
