摘要： A perpendicular magnetic recording head includes a first magnetic layer having a main magnetic pole exposed at a medium-facing surface that faces a recording medium; a second magnetic layer that faces the first magnetic layer with a nonmagnetic layer interposed therebetween; and a coil layer for applying a recording magnetic field to the first magnetic layer. The second magnetic layer includes a relatively thick edge portion, whereby the edge-write magnetic field is reduced and the external magnetic field resistance is increased.

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.

摘要： A magnetic head substrate is provided with a recording element having a main magnetic pole layer and a recording-side monitor element including a resistance film, a lead conductor located as a layer below the resistance film, and a contact conductor for conductively connecting the resistance film and the lead conductor. The resistance film is formed on the same plane as that for a lowermost layer of the main magnetic pole layer or a base layer from the same material as that for them, so as to straddle the surface position of a medium-facing surface in the height direction. The contact conductor and the lead conductor are disposed while being retreated to the back side of the above-described position in the height direction. The upper surface and the lower surface of the contact conductor are entirely in contact with the resistance film and are not exposed to the outside.

摘要： A perpendicular magnetic recording head is provided capable of suppressing the magnetic field attributable to the edge write phenomenon and improving resistance to an external magnetic field. The perpendicular magnetic recording head includes a magnetic layer that has a main magnetic pole on a surface facing a recording medium; a return yoke layer that is disposed on the magnetic layer with a nonmagnetic layer disposed therebetween and has a large width in the direction of the main magnetic pole; and a coil layer for applying a recording magnetic field to the magnetic layer. The return yoke layer is provided with such a shape that as seen in the plan view, the return yoke layer is exposed from the medium facing surface with a width not greater than the width in the track width direction of a protrusion region of the return yoke layer that covers the coil layer and the width of the return yoke layer gradually increases in the height direction from the medium facing surface.

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.
