    摘要： A soft magnetic film is formed of a CoFeNi alloy containing trace amounts of chlorine and sulfur as impurities. The stress of the soft magnetic film can be reduced effectively, specifically to 1,200 MPa or less, by adjusting the concentration ratio of chlorine to sulfur within the range from 1 to 60. In addition, variations in film stress can be reduced to provide higher yields of CoFeNi alloy films with low stresses.

    摘要： A perpendicular magnetic recording head includes a main magnetic pole layer and an auxiliary yoke layer that overlaps the main magnetic pole layer as viewed in a top view and is magnetically coupled to the main magnetic pole layer. The main magnetic pole layer includes a pole straight part exposed to an opposing surface opposite a recording medium, and a flared part that extends from the pole straight part in a height direction, the flared part broadening in a track width direction as the flared part extends in the height direction. The auxiliary yoke layer includes a flared part that extends from the recording medium-opposing surface, the flared part broadening in the track width direction as the flared part extends in the height direction. The flared part of the auxiliary yoke layer is disposed at a position located closer to the rear side in the height direction than the flared part of the main magnetic pole layer. The flared part of the main magnetic pole layer is formed at a flare angle greater than a flare angle of the auxiliary yoke layer.

    摘要： By forming a rearmost second coil piece so as to have a larger width in the track-width direction and a larger area than those of coil pieces, heat generated in a thin-film magnetic head can be effectively released to the rearmost coil piece. Thus, a temperature rise in the thin-film magnetic recording head can be further reduced than is possible today, thereby preventing the thin-film magnetic head from protrusion due to its thermal expansion.

    摘要： A thin-film magnetic head includes a lower core layer, a gap layer formed on the lower core layer with a lower pole layer therebetween, an upper pole layer formed on the gap layer, an upper core layer formed on the upper pole layer, and a Gd-defining layer for defining the depth in the height direction of the joint surface between the gap layer and the upper pole layer. The width in the track width direction of the gap layer is smaller than or equal to the width in the track width direction of the upper pole layer when viewed from the surface facing the recording medium. By employing such a thin-film magnetic head, the width in the track width direction of the gap layer can be decreased, and thus track narrowing is achieved.
