    摘要: A perpendicular magnetic recording head according to the present invention is composed of a first magnetic layer having a main magnetic pole exposed at a facing surface opposite a recording medium, a second magnetic layer adjacent to the first magnetic layer with an intermediary non-magnetic layer disposed therebetween, and a coil layer for applying a recording magnetic field to the first magnetic layer. Since the second magnetic layer has a shape including a substantially arched portion in its cross section along a height direction, it becomes possible to keep an Edge Write magnetic field in a low level and improve external magnetic field resistance.

    摘要: A thin-film magnetic head is capable of securing an insulating property and minimizing the projection of a recording element section due to heat expansion. The thin-film magnetic head includes a pair of magnetic layers disposed with a predetermined gap therebetween on a surface facing a recording medium. The layers are connected to each other along an inner part in a height direction from the medium-facing surface. A spiral recording coil is disposed between the pair of magnetic layers and wound around a connecting portion of the pair of magnetic layers. The recording coil includes a dense coil portion formed with a pitch smaller than that of the inner part in the height direction so as to be closer to the medium-facing surface than the connecting portion. An organic insulating layer is locally formed to fill coil gaps of the dense coil portion, and coil gaps other than those of the dense coil portion are filled with an inorganic insulating layer.
