A magnetic head has two poles separated by a gap and at least one saturable element. The saturable element joins the poles and is outside the gap and parallel to the gap. The head may be in the form of a matrix device having a number of poles mounted over a similar number of pads in the substrate. The saturable element may link two poles of the head by means of a pole of another magnetic head.

A method and system of magnetic recording of information elements on several parallel tracks whereby the recording of information elements on a track is accomplished by inducing a magnetic field having a predetermined direction in a zone on the track and, during this recording, inducing a magnetic field with a reverse direction in zones of the neighboring tracks. A winding (L0, L1, L2) of each head is coupled to at least two winding of neighboring heads. A control current transmitted to the head provides at least one current diverted towards the neighboring heads.
