    摘要： A heat-assisted magnetic recording head includes a slider, an edge-emitting laser diode fixed to the slider, and an external mirror provided outside the slider. The slider includes a magnetic pole, a waveguide, a near-field light generating element, and a substrate. The substrate has a top surface facing toward the magnetic pole, the near-field light generating element and the waveguide. The slider has a top surface that lies above the top surface of the substrate, at an end of the slider farther from the top surface of the substrate. The laser diode includes: an active layer; an emitting end face that lies at an end in a direction parallel to the plane of the active layer and includes an emission part for emitting laser light; and a bottom surface that lies at an end in a direction perpendicular to the plane of the active layer. The laser diode is arranged so that the bottom surface faces the top surface of the slider. The external mirror reflects the laser light emitted from the emission part toward the waveguide.

    摘要： A near-field light generating element accommodated in a groove of an encasing layer has an outer surface that includes a first end face including a near-field light generating part, a second end face opposite to the first end face, and a coupling portion that couples the first and second end faces. The coupling portion includes a top surface, and first and second side surfaces that decrease in distance from each other with increasing distance from the top surface. The first end face includes a first side located at an end of the first side surface, and a second side located at an end of the second side surface. Each of the first and second sides includes an upper part and a lower part continuous with each other. An angle formed between the respective lower parts of the first and second sides is smaller than that formed between the respective upper parts of the first and second sides.

    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.

    摘要： A plasmon generator has a front end face located in a medium facing surface of a magnetic head. The plasmon generator includes a first layer formed of a first metal material, a second layer formed of a second metal material, and a third layer formed of a third metal material. Each of the second and third layers has an end portion constituting part of the front end face. The first layer does not have any portion constituting part of the front end face. The first and second metal materials are higher in electrical conductivity than the third metal material. The third metal material is higher in Vickers hardness than the first and second metal materials. The first layer has a plasmon exciting part.
