Abstract

PURPOSE:To obtain a horizontal type head excellent in a high frequency characteristic by making first and second magnetic films into the laminated body of a soft magnetic film and a nonmagnetic film. CONSTITUTION:On a nonmagnetic substrate 21 excellent in a wear resistance such as glass, a conducting film 25 excellent in the wear resistance such as W is adhered, the first magnetic film 22 of the soft magnetic body such as an Fe-Ni type alloy is adhered on the conducting film 25, a part of the film 22 is cut and removed, a magnetic gap surface 26 in parallel to the node of the surface of the substrate 21 or having an angle is formed and the angle is equivalent to the azimuth angle of a magnetic head. On the whole surface, with a slanting sputtering method, a gap spacer 23 such as SiO2 is adhered and the spacer 23 remains only at the magnetic tap surface others are etched. Only on the first magnetic film 22, a photoresist film 31 is formed, the second magnetic film 24 such as Fe-Ni type alloys is adhered on the conducting film 25 with a electric plating method and a first magnetic body and the height are made into the same. Next, after the resist film 31 is removed, a nonmagnetic film 28 for protecting a head such as Al2O3 is adhered on magnetic bodies 22 and 24 and a winding window hole 29 is drilled and a winding 30 is executed.
