摘要： An encasing section that accommodates a pole layer includes an encasing layer having an encasing groove, and a nonmagnetic film disposed in the encasing groove at a position between the encasing layer and the pole layer. The pole layer includes a track width defining portion and a wide portion. The distance from a medium facing surface to the boundary between the track width defining portion and the wide portion is within a range of 10 to 300 nm. The track width defining portion has a first side surface and a second side surface, while the wide portion has a third side surface contiguous to the first side surface, and a fourth side surface contiguous to the second side surface. The encasing layer has a first wall surface and a second wall surface that form the encasing groove. The distance between the third side surface and the first wall surface is smaller than the distance between the first side surface and the first wall surface, and the distance between the fourth side surface and the second wall surface is smaller than the distance between the second side surface and the second wall surface.

摘要： A method of manufacturing magnetic heads comprises the steps of: fabricating a magnetic head substructure by forming components of a plurality of magnetic heads on a single substrate so that a plurality of rows of pre-head portions that will be the respective magnetic heads later are aligned in the substructure; and fabricating the magnetic heads by separating the pre-head portions from one another through cutting the substructure. Indicator sections are formed in the substructure. The indicator sections include first indicators and second indicators. Widths of the first and second indicators are equal in an imaginary surface indicating a target location of the medium facing surfaces. One of the widths of the first and second indicators decreases while the other increases with shifts in position along the direction orthogonal to the medium facing surfaces.

摘要： A thermally-assisted magnetic recording head includes a medium facing surface, a main pole, a waveguide, and a plasmon generator. A second metal layer of the plasmon generator includes a second front end facing the medium facing surface. A third metal layer of the plasmon generator includes a narrow portion located on the second metal layer. The narrow portion includes a front end face located in the medium facing surface and configured to generate near-field light from a surface plasmon, and a rear end opposite the front end face. The rear end is located farther from the medium facing surface than is the second front end.

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.
