Claims

[Scope of utility model registration request]

means for dividing and reproducing a recording signal recorded on the same recording track of a magnetic tape in the width direction of the recording track to form a track division signal; and recording of the recording signal based on a difference signal between the track division signals. 1. An azimuth detection device for a magnetic head, comprising a detection means for detecting an azimuth relationship between a recording head used for recording and a reproduction head for dividing and reproducing the recording signal.
