Abstract
A composite type magnetic head suitable for use in a magnetic recording and playback apparatus includes a main gap having an azimuth preset for recording and/or playing back a signal and a pair of pseudo gaps, each having an azimuth which is arranged to be not parallel to the main gap. The azimuth of the pseudo gaps is also arranged not to be parallel to the azimuth of the signal recorded on a recording track. With the above-described structure, the output level of a signal produced by the pseudo gap when recording or reproducing is reduced such that interference which the pseudo gap exerts upon a signal played back by the main gap is reduced, thereby eliminating deterioration in the signal-to-noise ratio.
