    摘要： A thin-film magnetic head includes a first magnetic layer, a flat, spiral-shaped coil, a toroidal-shaped insulating layer covering the coil, and a second magnetic layer touching the insulating layer and disposed to sandwich part of the coil between itself and the first magnetic layer. The second magnetic layer has a recessed portion that enters a space inside the insulating layer. In the recessed portion, the bottom surface of the second magnetic layer includes a first flat portion a part of which touches the top surface of the first magnetic layer, while the top surface of the second magnetic layer includes a second flat portion located in the space and substantially parallel to the first flat portion. In a cross section that divides each of the first and second magnetic layers into two equal portions, the second flat portion is 0.3 to 6 μm in length, and a distance from an edge of the interface between the top surface of the first magnetic layer and the first flat portion closer to the medium facing surface to an edge of the top surface of the first magnetic layer farther from the medium facing surface is 0.35 to 0.95 times the length of the first flat portion.

    摘要： A magnetic head incorporates: a medium facing surface; a coil; a pole layer; first and second shields disposed to sandwich the pole layer therebetween; a first gap layer disposed between the first shield and the pole layer; a second gap layer disposed between the second shield and the pole layer; and a substrate. The first shield is located closer to the substrate than the second shield. The magnetic head further incorporates an antireflection film disposed between the first shield and the first gap layer or between the first gap layer and the pole layer. The pole layer is formed by frame plating.

    摘要： The present invention relates to a shaping method of a thin film layer and a manufacturing method of a perpendicular recording magnetic head using the same. In the thin film layer shaping method according to the present invention, since a second thin film of a lower etching rate is etched by a preliminary etching amount allowing for a difference between the etching rate of the second thin film and an etching rate of a first thin film in side-by-side relationship with each other, both the first and second thin films can be etched by the same etching amount through a subsequent etching step, so that the thin film layer can be shaped into a given shape. Thus, the surface of the thin film layer can be planarized.

    摘要： A method for analyzing proteins with the use of electrophoresis is provided, which makes it possible to rapidly and conveniently analyze a great variety of proteins with high sensitivity. The method for analyzing a protein in a sample comprises setting a sample in a carrier for electrophoresis, performing electrophoresis for the sample using a buffer for electrophoresis in which a labeling compound represented by formula I: wherein R1 is an aryl group or a heteroaryl group that may be substituted, R2 is a heterocyclic group that may be substituted, and n is an integer between 1 and 5, is dissolved, and then detecting a complex of the compound of formula I and the protein via spectrophotometrical measurement.
