Abstract

PURPOSE:To efficiently generate a magnetic field by constituting the titled magnetic head so that height of a soft magnetic pattern which becomes a shield layer of a magneto-resistance effect type head becomes lower than a height of the opposed shield pattern. CONSTITUTION:A height of a shield pattern 21 which has been formed on a substrate 1 is lower than a height of the lower part magnetic pole pattern, therefore, a step difference is generated in the lower part magnetic pole pattern 51 which has been laminated through an insulating layer 3. Thereafter, an insulating layer 6 and a conductor coil 7 are laminated successively and flattened, and in the end, the upper part magnetic pole 8 and a protective film 9 are laminated. Also, the conductor coil 7 is formed and a flattened layer 61 is laminated, and thereafter, a part thereof is brought to etching to a tapered shape, and a step difference part is formed in the upper part magnetic pole. In this case, by providing the height of the magnetic pole parallel part so as to become lower than the height of the shield pattern, it does not occur that an interval between the upper part magnetic pole and the lower part magnetic pole becomes narrow due to a step difference. In such a way, a leakage of a magnetic flux between the magnetic poles can be reduced, and a magnetic field can be generated efficiently at the tip of the magnetic pole.
