Abstract

PURPOSE:To increase the effect of bias DC magnetic field, by laminating nonmagnetic substance insulating thin film on the substrate, forming the hard magnetic thin film of strip paper shape lengthwise, laminating the nonmagnetic insulating film on it, and laminating the magnetic resistance effect element film (MR). CONSTITUTION:A nonmagnetic insulating thin film 2 such as SiO2 is formed on the substrate 1 and a hard magnetic thin film 3 in parallel with lengthwise a strip- shaped MR element film 5 is formed on it by using magnetic thin film of metaloxide such as Fe-Co-Cu and magnetic thin film of Co-P as masks through the lamination of vapor or electrodeposition. Next, the film 4 is laminated with SiO2, and the film 5 such as Fe-Ni is formed on the film 4 in strip shape. A conductive thin film 6 such as Au is provided at lengthwise ends 51, 52 of the film 5. A nonmagnetic insulating thin film 7 is laminated on the film 6 and the MR magnetic head is formed by providing the protective plate 8 further. In applying a bias DC magnetic field to the MR element film 5 from the film 3, since smooth surface is obtained for the films 3, 4, 5, sufficient output can be obtained by applying further smaller bias magnetic field.
