Abstract

An integrated magnetic head including a thin layer structure. The thin layer structure contains, in the edge of the structure constituting the reading and/or writing face of the magnetic head, two pole pieces separated by a gap and aligned longitudinally. The pole pieces are contained in the transverse direction with respect to the structure between parallel planes of the thin layer structure. The magnetic head bas two layers of wear-resistant material which frame the thin layer structure to reinforce the wear resistance of the reading and/or writing face.
