    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: The present invention relates to a method for manufacturing a perpendicular recording magnetic head, more particularly, to a method for manufacturing a main magnetic pole film with a wrap-around structure. After the main magnetic pole film with a body portion of a large plane area and a write magnetic pole portion continuous with the body portion and elongated in a plane area is formed on one face of a non-magnetic film, the one face of the non-magnetic film is etched. Then, it also includes the step of further etching the one face of the non-magnetic film with an undercut, which is caused by the etching around the body portion and beneath the write magnetic pole portion, being at least partially filling with an organic filler.
