    摘要: A thin-film magnetic head includes a slider substrate and a write element. The slider substrate has an air bearing surface at one side thereof. The write element has a recording magnetic pole film. The recording magnetic pole film is disposed on a plane crossing the air bearing surface over the slider substrate and has a large-width portion and a small-width portion continuously arranged in the named order toward the air bearing surface. The small-width portion has a smaller width than the large-width portion. Of the large-width portion and the small-width portion, at least the small-width portion has a first portion and a second portion. The second portion is continuous with an upper end of the first portion and has both side faces inclined in such a direction as to increase the width. An external angle of the first portion formed by a plane parallel to a bottom face and the side face is larger than an external angle of the second portion formed by a plane parallel to the bottom face and the side face.

    摘要: A main magnetic pole includes a first part extending from a medium facing surface to a point at a predetermined distance from the medium facing surface, and a second part other than the first part. An accommodation part for accommodating the main magnetic pole includes: a first layer having a groove; a second layer lying between the first layer and the main magnetic pole in the first layer's groove; and a third layer interposed in part between the second layer and the main magnetic pole in the first layer's groove. The second layer is formed of a metal material different from a material used to form the first layer. The third layer is formed of an inorganic insulating material. The second and third layers lie between the first layer and the first part. The second layer lies between the bottom of the first layer's groove and the second part, but the third layer does not. The distance between the bottom of the first layer's groove and the second part is smaller than that between the bottom and the first part.

    摘要: The present invention relates to a magnetic head, a manufacturing method therefor, a head assembly, and a magnetic recording/reproducing apparatus. According to the present invention, it includes a magnetic pole layer, a non-magnetic layer, a trailing gap layer, and a trailing shield layer. The magnetic pole layer has a pole tip exposed on a magnetic medium-facing surface. The non-magnetic layer is laid on the magnetic pole layer. The trailing shield layer is exposed on the magnetic medium-facing surface and laid over the magnetic pole layer and the non-magnetic layer with the trailing gap layer between. The magnetic pole layer and the non-magnetic layer have a continuous tapered face opposed to a lower side of the trailing shield layer. Moreover, the tapered face extends from a trailing edge of the pole tip at a constant inclination angle.

    摘要: The micropattern formation of the invention comprises forming a resist pattern, and then forming a carbon-containing film on the surface of the resist pattern, followed by ashing of the carbon-containing film and a portion of the resist surface constituting the resist pattern. Thus, the discharge state of ashing just after the initiation of discharge is so stabilized that the ashing rate distribution can be improved, and sensitive pattern slimming can be implemented with ease and high precision.
