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 manufacturing method for a waveguide includes forming a core including a first layer and a second layer. The first layer has a top surface including a first region with which a bottom surface of the second layer is in contact, and a second region with which the bottom surface of the second layer is not in contact. Forming the core includes the steps of: forming an initial first layer; forming an etching stopper layer on the second region of the initial first layer; forming an initial second layer on the initial first layer and the etching stopper layer; etching the initial second layer and the initial first layer so as to make the initial first layer into the first layer; and etching the initial second layer until the etching stopper layer is exposed, so as to make the initial second layer into the second layer.

摘要： A thermally-assisted magnetic recording head includes a main pole and a plasmon generator. The main pole has a front end face located in the medium facing surface. The plasmon generator has a near-field light generating surface located in the medium facing surface. The front end face of the main pole includes a first end face portion and a second end face portion. The second end face portion is located farther from the near-field light generating surface than is the first end face portion, and is greater than the first end face portion in width in the track width direction. The first end face portion and the near-field light generating surface are equal in width.

摘要： A method of taper-etching a layer to be etched that is made of a dielectric material and has a top surface. The method includes the steps of: forming an etching mask with an opening on the top surface of the layer to be etched; and 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 intersecting at a predetermined angle is formed in the layer to be etched. The step of taper-etching employs an etching gas containing a first gas contributing to the etching of the layer to be etched and a second gas contributing to the deposition of a sidewall protective film, and changes, during the step, the ratio of the flow rate of the second gas to the flow rate of the first gas so that the ratio increases.
