摘要： A process for producing a double magnetic head with two head gaps with opposite azimuths by forming a first magnetic head with a first head gap having a predetermined inclination angle on a first substrate and a second magnetic head having a second head gap with a second inclination angle on a second substrate and etching a first recess along the first head. The second head is received in the first recess and a second recess is etched along the second head to receive the first head. Subsequently, one of the heads is reversed and the first head is fitted into the second recess and the second head into the first recess so that the first and second inclination angles are opposed in a common reference frame thereby providing opposite azimuth angles.

摘要： 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.
