Abstract

PURPOSE:To prevent the greater steps together with the less number of laminating layers of thin film, and to avoid troubles such as open wire of coil conductors, by providing the head elements for recording and reproduction at the both sides of the substrate separately. CONSTITUTION:The reproducing head element 1 consisting of the lower shield film 3 such as permalloy, insulation film 7, stripe shape magnetic resistance element 5, bias film 6 such as permanent magnet thin film, insulation layer 8 and upper shield film 4, which uses the magnetic resistance effect, is provided at one side of the substrate 2, by evaporation, etching or the like. The recording head element 9 consisting of the lower magnetic substance 10, coil conductor 12 in common use with the head gap and upper magnetic substance 11 is similarly provided at another side of the substrate 2. In this integrated magnetic head 14, the track width W and the track position of the elements 1, 9 are made equal.
