The magnetic recording and reproducing apparatus records two signals, such as the chrominance and luminance signals, such as the chrominance and luminance signals of a colour television signal by two magnetic heads in two tracks on a magnetic recording tape. The two tracks are made to overlap, at least partly, so as to increase the utilization of tape. The signals to be recorded are given substantially different frequencies to permit their reproduction without interference from each other. To avoid interference between the signals recorded in the overlapped tracks, the core gap of the head for recording and reproducing the relatively LF signal is made wider than the core gap of the other head, and the latter core gap extends transversely at right angles to the longitudinal direction of its respective track while the relatively wide core gap extends obliquely w.r.t. its track.
