ABSTRACT:
A magnetic head consists of a magnetic flux converging core having a magnetic gap and a magnetoresistive effect element which forms a magnetic circuit and which is arranged in the same plane as the magnetic gap. The direction of thickness of the magnetic circuit is aligned with the direction of width of a track of a record medium, and shielding plates of ferromagnetic material are arranged on both sides of the plane.
