摘要： A first side shield has a first sidewall and a second sidewall. A second side shield has a third sidewall and a fourth sidewall. The distance between the first sidewall and the third sidewall decreases with increasing proximity to the top surface of a substrate. The second and fourth sidewalls are close to perpendicular to the top surface of the substrate. Each of the second and fourth sidewalls has an edge farthest from the top surface of the substrate, the edge being parallel to the medium facing surface. The main pole has a first, a second, a third and a fourth side surface. The first side surface is opposed to the first sidewall. A portion of the second side surface is opposed to the second sidewall. The third side surface is opposed to the third sidewall. A portion of the fourth side surface is opposed to the fourth sidewall.

摘要： A method of manufacturing the plasmon generator includes the steps of: forming a base part made of a dielectric material; forming a metal film that is to later become the plasmon generator; and forming a filler layer made of a dielectric material. The base part includes a base surface and a protruding part that protrudes from the base surface. The protruding part has a top surface that is different in level from the base surface, and a first sidewall connecting the top surface of the protruding part to the base surface. The metal film includes an adhesion part adhering to the first sidewall. The filler layer has a second sidewall disposed such that the adhesion part is interposed between the first sidewall and the second sidewall.

摘要： In a method of manufacturing a near-field light generator, a structure including a core and a polishing stopper layer disposed on the top surface of the core is formed on a first cladding layer. Next, a cladding material layer is formed to cover the first cladding layer and the structure. The cladding material layer is then polished until the polishing stopper layer is exposed. Next, the polishing stopper layer is removed so that the cladding material layer has a protruding portion protruding upward to a higher level than the top surface of the core. The cladding material layer is then polished so as to remove the protruding portion and thereby make the cladding material layer into a second cladding layer. Then, a third cladding layer and a plasmon generator are formed.

摘要： A magnetic head includes a main magnetic pole, a shield having an end face located in a medium facing surface to wrap around an end face of the main magnetic pole, and a gap part provided between the main magnetic pole and the shield. The shield includes a bottom shield, two side shields, and a top shield. The gap part includes first and second gap layers. In a manufacturing method of the magnetic head, a mold is formed on the top surface of the bottom shield, the mold having a shape determined by photolithography and being intended to be removed later. Next, the two side shields are formed on the top surface of the bottom shield by performing plating without forming a seed layer. Next, the mold is removed and then the first gap layer, the main magnetic pole, the second gap layer, and the top shield are formed in succession.
