    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： 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 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 near-field light generating layer has a laminated structure in which a first thin-film metal layer formed in a thin film form along a direction intersecting the medium-opposing surface and a second thin-film metal layer formed in a thin film form and formed using a second metal larger in hardness than a first metal forming the first thin-film metal layer are alternately laminated. Further, in the second thin-film metal layer, a defect part is formed, the defect part is a part smaller in thickness than another part or is a hole part, and a flat layer part other than the defect part surrounds the defect part.
