    摘要: A magnetic head includes a coil, a main pole, a write shield, a gap section, and a return path section. The main pole has a top surface including an inclined portion and a flat portion. The coil includes a specific coil element. The specific coil element has a front end portion, and an inclined surface contiguous with the front end portion. The write shield includes a top shield layer located on the front side in the direction of travel of a recording medium relative to the main pole, and located closer to a medium facing surface than the specific coil element. The top shield layer is located on the rear side in the direction of travel of the recording medium relative to an imaginary plane including the inclined surface of the specific coil element.

    摘要: A magnetic head includes a coil, a main pole, a write shield, a first insulating film, and a second insulating film. The coil includes a specific coil element. The main pole has a top surface including an inclined surface portion and a flat surface portion. The write shield includes an inclined portion. The inclined portion includes a first portion opposed to the inclined surface portion, and a second portion located farther from a medium facing surface than the first portion. The specific coil element includes an interposition part interposed between the flat surface portion and the second portion. The first insulating film is interposed between the inclined surface portion and the first portion of the inclined portion, and between the interposition part and the second portion of the inclined portion. The second insulating film is interposed between the first insulating film and the second portion of the inclined portion.

    摘要: A plasmon generator configured to excite a surface plasmon based on light includes a first portion formed of a first metal material and a second portion formed of a second metal material different from the first metal material. The plasmon generator has a front end face. The front end face includes a near-field light generating part that generates near-field light based on the surface plasmon. The second portion includes an end face located in the front end face. The second metal material satisfies at least one of the following requirements: a lower ionization tendency than that of the first metal material; a lower electrical conductivity than that of the first metal material; and a higher Vickers hardness than that of the first metal material.

    摘要: In a method of forming a main pole, an initial accommodation layer is etched by RIE using a first etching mask having a first opening, whereby a groove is formed in the initial accommodation layer. Next, a part of the initial accommodation layer including the groove is etched by RIE using a second etching mask having a second opening, so that the groove becomes an accommodation part. The main pole is then formed in the accommodation part. The first etching mask has first and second sidewalls that face the first opening and are opposed to each other at a first distance in a track width direction. The second etching mask has third and fourth sidewalls that face the second opening and are opposed to each other at a second distance greater than the first distance.

    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 method of manufacturing a plasmon generator includes the steps of: an initial film made of a metal polycrystal and including a pre-plasmon-generator portion that later becomes the plasmon generator; heating the initial film with heating light so that a plurality of crystal grains constituting the metal polycrystal grow at least in the pre-plasmon-generator portion; stopping the heating of the initial film; and forming the plasmon generator by processing the initial film after the step of stopping the heating. The step of forming the plasmon generator includes the step of providing the pre-plasmon-generator portion with a front end face that generates near-field light.
