    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 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.

    摘要: The present invention provides a manufacturing method of a magneto-resistance effect element, in which the step coverage of a formed film can be enlarged and also the film can be deposited in a low temperature range. In an embodiment of the present invention, an insulating protective layer is formed on a multilayered structure by a plasma CVD apparatus in which a plasma source and a film deposition chamber are separated from each other by a partition wall plate. According to the present method, it is possible to deposit the protective layer without inviting the degradation of a magnetic characteristic and also to perform low temperature film deposition even at a temperature lower than 150° C. Hence, it is possible to deposit the protective layer while leaving resist and also to reduce the number of steps in the manufacturing of the magneto-resistance effect element having a multilayered structure.
