A helical scan type magnetic recording/reproducing apparatus in which a magnetic tape is guided helically around a rotary magnetic head assembly over an angular range approximating to 360.degree.. Two magnetic heads are disposed relatively closely to each other at an angle smaller than 180.degree.. The rotary magnetic heads assembly performs a single complete rotation for a unit period, for example, one field period. In recording, video signal of the unit period undergoes time axis compression to be compressed to a period corresponding to a scanning period of the heads during which the magnetic heads are in contact with the magnetic tape in each rotation of the head assembly and supplied to alternately the magnetic heads which are so designed that the azimuth angles of the respective gaps differ from each other. Alternatively, the video signal is separated into a luminance signal and a chrominance signal, wherein the former is supplied to one of the magnetic heads while the latter is simultaneously supplied to the other.
A video signal recording/reproducing apparatus of helical-scan type, in which a video signal is recorded on a magnetic tape in successive tracks which are inclined to the longitudinal direction of the tape, comprising:
