    摘要: A magnetic head includes first to third coils, a main pole, a write shield, first and second yoke layers, and first and second coupling parts. The first and second yoke layers are magnetically connected to the write shield. The first yoke layer is located on the leading side relative to the main pole, whereas the second yoke layer is located on the trailing side relative to the main pole. The first coupling part magnetically couples the main pole and the second yoke layer to each other. The second coupling part magnetically couples the first yoke layer and the second yoke layer to each other. The first coil is wound around the first coupling part, whereas the second and third coils are wound around the second coupling part.

    摘要: A method of taper-etching a layer to be etched that is made of SiO2 or SiON and has a top surface. The method includes the step of forming an etching mask with an opening on the top surface of the layer to be etched, and the step of taper-etching a portion of the layer to be etched, the portion being exposed from the opening, by reactive ion etching so that a groove having two wall faces that intersect at a predetermined angle is formed in the layer to be etched. The etching mask is formed of a material containing elemental Al. The step of taper-etching employs an etching gas that contains a main component gas, which contributes to the etching of the layer to be etched, and N2.

    摘要: A thermally assisted magnetic head includes a main magnetic pole layer, a near-field light generating layer having a generating end part generating near-field light arranged within a medium-opposing surface, and an optical waveguide guiding light to the near-field light generating layer. The thermally assisted magnetic head includes a base layer which a base groove part having a width gradually getting smaller along a depth direction and extending in an intersecting direction intersecting with the medium-opposing surface is formed. The near-field light generating layer has an in-groove generating layer formed inside of the base groove part. The in-groove generating layer is formed along an inner wall surface of the base groove part and has a thin-film like structure.

    摘要: A thin-film magnetic head is constructed such that a main magnetic pole layer, a write shield layer, a gap layer, and a thin-film coil are laminated on a substrate. The write shield layer has an opposing shield part opposing the main magnetic pole layer and a front shield part. The front shield part is connected to the opposing shield part without straddling the thin-film coil. Besides, the front shield part has a shield front end face disposed in the medium-opposing surface and a shield upper end face formed distanced from the medium-opposing surface. Further, the front shield part has a shield connecting part. The shield front end face is connected to the shield upper end face by the shield connecting part.

    摘要: A magnetic head includes a pole layer, and an encasing layer having a groove that accommodates the pole layer. A manufacturing method for the magnetic head includes the steps of forming a nonmagnetic layer that will later undergo formation of the groove therein and will thereby become the encasing layer; forming the groove in the nonmagnetic layer so that the nonmagnetic layer becomes the encasing layer; and forming the pole layer such that the pole layer is accommodated in the groove of the encasing layer. The nonmagnetic layer is formed of Al2O3. The step of forming the groove in the nonmagnetic layer includes the step of taper-etching the nonmagnetic layer by reactive ion etching with an etching gas containing at least BCl3 and N2 among BCl3, Cl2 and N2.

    摘要: A heat-assisted magnetic recording head includes a slider, an edge-emitting laser diode fixed to the slider, and an external mirror fixed to the laser diode. The laser diode has an emitting end face that includes an emission part for emitting laser light; a mounting surface that lies at an end in a direction perpendicular to the plane of an active layer and faces the slider; and a rear surface opposite to the mounting surface. The external mirror includes: a first to-be-fixed part disposed along the emitting end face; a second to-be-fixed part disposed along the rear surface; and a coupling part that couples the first and second to-be-fixed parts to each other. The first to-be-fixed part has a reflecting surface that reflects the laser light emitted from the emission part toward the waveguide.
