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=TpN(RPS)/sin
, 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.
