ABSTRACT:
In a magnetic recording and reproducing device having a1chhead and a2chhead, an azimuth recording operation is carried out on an obliquely evaporated magnetic tape. Angles θ1and θ2formed by a direction of a head azimuth of the1chhead and the2chhead and a longitudinal direction of the magnetic tape are respectively set to angles at which an output difference between a reproducing signal of a track recorded by the1chhead and a reproducing signal of a track recorded by the2chhead is located within three decibels. Thus, an output difference between the two magnetic heads is reduced while the loss of electromagnetic conversion is reduced.
