    摘要: A soft magnetic alloy thin film includes a fine crystalline phase and an amorphous phase. The fine crystalline phase includes an average crystalline grain size of 10 nm or less in diameter and has body-centered cubic structure mainly composed of Fe. The amorphous phase has a nitrogen (N) compound as the main composition and occupies at least 50% of the structure of the thin film. An element M is incorporated at least in the amorphous phase, and includes at least one element selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, W, and rare earth metal elements. A plane-type magnetic device is made using this thin film.

    摘要: At both sides of an element portion, a first hard bias layer having a higher residual magnetization Mr and a second hard bias layer having a higher coercive force Hc are deposited in that order from the bottom with one end of the first hard bias layer being closed close to a free magnetic layer. A film thickness ratio of the first hard bias layer in a whole hard bias layer is from 35% to 75%. This stabilizes magnetization in the free magnetic layer to reduce asymmetry, thus enabling improvement in stability of reproducing characteristics including noise suppression.

    摘要: A thin film magnetic head comprises a lower gap layer composed of an adhesion layer formed of Al2O3 or the like, an AlN film having a high thermal conductivity and a protective layer formed of Al2O3 or the like. Since the lower gap layer comprises the AlN film, it has an extremely high thermal conductivity as compared to conventional equivalents. Accordingly, heat generated from a magnetroresistive element layer can be escaped through the lower gap layer to a lower shield layer so as to inhibit the temperature of element from elevating and to obtain a satisfactory regeneration sensitivity.

    摘要: A thin film magnetic head includes a gap layer which may be made of a SiON film to increase Young's modulus E to about 123.3 (GPa) or more. As a result, the gap layer is less pushed from a surface facing a recording medium in the height direction during lapping of the surface facing the recording medium, thereby decreasing the amount of protrusion of the gap layer from the facing surface as compared with a conventional magnetic head.
