Abstract
In a magnetic recording and reproducing device having ahead and ahead, an azimuth recording operation is carried out on an obliquely evaporated magnetic tape. Angles θand θformed by a direction of a head azimuth of thehead and thehead 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 thehead and a reproducing signal of a track recorded by thehead is located within three decibels. Thus, an output difference between the two magnetic heads is reduced while the loss of electromagnetic conversion is reduced.
