摘要： A magnetic head and a manufacturing method thereof which can suppress side fringing and permeation of a recording magnetic field in the first direction while maintaining the intensity of a recording magnetic field. By making a length of a trailing upper surface of a front portion in a height direction longer than a length of a leading lower surface of the front portion in the height direction, a generated magnetic field of the trailing upper surface can be comparatively weakened, to suppress side fringing and magnetic field permeation of a recording magnetic field. The recording magnetic field can be kept large enough by shortening the length of the leading lower surface in the height direction to intensify a generated magnetic field generated from the leading side.

摘要： A perpendicular magnetic recording head includes a main pole layer and a return path layer that are exposed from a medium-facing surface of the recording head facing a recording medium and that face each other with a predetermined gap therebetween at the medium-facing surface. A coil layer applies a recording magnetic field to the main pole layer and the return path layer. The return path layer includes a gap adjusting layer and a main layer stacked in that order from a side facing the main pole layer. The gap adjusting layer is positioned so as to face the main pole layer and the recording medium, and is made of a magnetic material having a resistivity lower than resistivities of the main layer and the main pole layer.

摘要： A perpendicular magnetic recording head includes a nonmagnetic insulating layer and a main magnetic pole layer disposed on the nonmagnetic insulating layer. The main magnetic pole layer includes a pole straight part exposed in 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 broadens in a track width direction as the flared part extends in the height direction. The pole straight part of the main magnetic pole layer as viewed from the opposing surface has a trapezoidal shape over its entire length, the trapezoidal shape being narrowed at the nonmagnetic insulating layer-side. The flared part as viewed from the opposing surface has a trapezoidal shape at least at a junction with the pole straight part, the trapezoidal shape being narrowed at the nonmagnetic insulating layer-side.
