    摘要： A near-field light generating element has an outer surface. The outer surface includes a bottom surface, first and second inclined surfaces, an edge part that connects the first and second inclined surfaces to each other, and a front end face located in a medium facing surface. The front end face includes a first side that lies at an end of the first inclined surface, a second side that lies at an end of the second inclined surface, and a tip that is formed by contact of the first and second sides with each other and forms a near-field light generating part. Each of the first side and the second side has a lower part and an upper part that are continuous with each other. An angle formed between the upper part of the first side and the upper part of the second side is smaller than that formed between the lower part of the first side and the lower part of the second side.

    摘要： A thin-film magnetic head including a main magnetic pole layer having a magnetic pole end part on a side of a medium-opposing surface opposing a recording medium; a write shield layer opposing the magnetic pole end part to form a recording gap layer on the medium-opposing surface side; a thin-film coil wound about the write shield layer or the main magnetic pole layer; and a base insulating layer formed with a magnetic pole forming depression, including a very narrow groove defining a form of the magnetic pole end part and a main depression integrally extending from an end part of the very narrow groove remote from the medium-opposing surface. A stepped part is formed at a boundary between a bottom face of the main depression and a bottom face of the very narrow groove. The main magnetic pole layer is the only magnetically functional layer in the depression.

    摘要： A near-field light generator includes: a waveguide; a clad layer having a penetrating opening and disposed on the waveguide; a plasmon generator accommodated in the opening; and a dielectric film interposed between the plasmon generator and each of the waveguide and the clad layer. In a method of manufacturing the near-field light generator, an initial clad layer is initially formed on the waveguide, and then the initial clad layer is taper-etched by RIE to form a recess that does not reach the top surface of the waveguide. Subsequently, the recess is etched by wet etching until the top surface of the waveguide is exposed in part. Next, the dielectric film is formed in the opening, and the plasmon generator is formed on the dielectric film.

    摘要： A magnetic head includes a side shield layer and an encasing layer. The side shield layer has a first end face located in the medium facing surface, a second end face opposite to the first end face, and a first groove accommodating a portion of a pole layer. The first end face includes two portions located on both sides of an end face of the pole layer that are opposite to each other in a track width direction. The encasing layer is formed of a nonmagnetic material and disposed on a side of the side shield layer opposite to a medium facing surface. The encasing layer has a front end face touching the second end face of the side shield layer, and a second groove accommodating another portion of the pole layer. The distance from the medium facing surface to an arbitrary point on the second end face of the side shield layer decreases with decreasing distance from the arbitrary point to the top surface of a substrate.

    摘要： A thin-film magnetic head structure has a configuration adapted to manufacture a thin-film magnetic head configured such that a main magnetic pole layer including a magnetic pole end part on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the magnetic pole end part so as to form a recording gap layer on the medium-opposing surface side, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated. The main magnetic pole layer has an end face joint structure where respective end faces of the magnetic pole end part and a yoke magnetic pole part having a size greater than that of the magnetic pole end part are joined to each other, and a surface with a flat structure on a side closer to the thin-film coil.
