Abstract
A helical scan type magnetic recording and reproducing apparatus comprises a rotary body which is wrapped with a magnetic tape on an outer peripheral surface thereof over a predetermined angular range and has a tape guide for guiding a part of the magnetic tape, and n pairs of rotary heads mounted on the rotary body. Each pair out of the n pairs of rotary heads is constituted by two rotary heads which are mounted at mutually opposite positions on a rotational plane of the rotary body at the same height position, and each pair out of the n pairs of rotary heads is mounted at different positions in an axial direction of the rotary body. The n pairs of rotary heads simultaneously record a luminance signal and two kinds of signals constituting a color video signal on n groups of tracks which are mutually separated in the tape width direction, so that the luminance signal is recorded on one group of tracks which is closest to the tape guide of the rotary body in order to minimize a jitter in the luminance signal which is reproduced.
