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： In a perpendicular magnetic write head manufacturing method a magnetic layer is formed on a substrate. On the magnetic layer, first and second nonmagnetic layers are formed with different materials. A mask pattern is formed on the second nonmagnetic layer, and the second nonmagnetic layer in a region not covered with the mask pattern is removed Thereby, the patterned second nonmagnetic layer is formed while leaving the first nonmagnetic layer. The mask pattern is removed and a milling process is selectively performed on the first nonmagnetic layer and the magnetic layer with the patterned second nonmagnetic layer as a mask to remove all of the first nonmagnetic layer in an exposed region and to dig down the magnetic layer in the exposed region, thereby forming a main magnetic pole layer having an inclined part whose thickness decreases with distance from an edge position of the patterned second nonmagnetic layer.

The method for manufacturing a perpendicular recording magnetic head according to the present invention includes first to third steps. At the first step, a main magnetic pole layer is formed on a foundation layer. At the second step, a main magnetic pole forming mask whose recording-medium-facing surface is of an inverted trapezoidal shape is formed on the main magnetic pole layer. At the third step, a main magnetic pole whose recording-medium-facing surface is of an inverted trapezoidal shape is formed by performing ion milling on a laminated structure including the foundation layer and the main magnetic pole layer from a direction which makes a given angle with a lamination direction according to a bevel angle of the inverted trapezoidal shape.

摘要： A thin film magnetic head includes a main magnetic pole layer conducting a magnetic flux to the recording medium so that the recording medium an be magnetized in a direction orthogonal to a surface thereof; a return yoke layer disposed on a trailing side of the main magnetic pole layer; an intermediate protective layer partially disposed on a magnetic shield layer; and a thermal expansion suppressing layer having an edge located on the intermediate protective layer and being in contact with the return yoke layer in an area where the intermediate protective layer is not formed. If the thin film magnetic head is affected by ambient temperature environment, the thermal expansion suppressing layer suppresses the shift of the main magnetic pole layer and the return yoke layer toward the air bearing surface. This suppresses thermal protrusion from occurring on the thin film magnetic head due to ambient temperature environment.

摘要： A thin film magnetic head is provided to reduce excess magnetostatic leakage field in order to generate a sufficient recording magnetic field. The pole end portion has a width to define a recording track width. The pole rear portion has one end which is magnetically connected with the pole end portion at or in the vicinity of an edge portion of an insulating film and defines a first flare point, the other end which is connected with the upper yoke portion and defines a second flare point, and both side edges in the track width direction which are inclined so that the width in the track width direction gradually increases from the second flare point toward the first flare point. The width of the pole end portion at the first flare point is smaller than the maximum width of the pole rear portion.
