ABSTRACT:
A combined-type thin film magnetic head in which a reproducing head portion including a magnetoresistive device and an inductive magnetic head are laminated. A coil support portion made of the same plated layer that forms an upper gap layer of the reproducing head portion having the magnetoresistive device and a lower core portion separated from the magnetic material layer by a gap .delta. are formed on the surface of the upper gap layer. The coil support portion and the lower core portion have areas that enable a coil layer to be formed so that the coil layer is enabled to be formed on a region having no step. An upper core layer is formed on the lower core portion in such a manner that the coil layer is held therebetween. A magnetic gap is formed between the two core layers. Since the magnetic passage of the lower core portion has a small cross sectional area, the inductance of the magnetic circuit can be lowered.
