    摘要： A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a core part. The return path section includes a yoke part magnetically connected to the write shield, and a coupling part located away from a medium facing surface and magnetically coupling the yoke part and the main pole to each other. The first coil is located on the front side in the direction of travel of a recording medium relative to the main pole and wound around the coupling part. The core part is located farther from the medium facing surface than is the coupling part, and is magnetically connected to the main pole. The second coil is located on the front side in the direction of travel of the recording medium relative to the main pole and wound around the core part.

    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 plasmon generator has a front end face, a first metal layer, a second metal layer, and an intermediate layer. The front end face generates near-field light based on a surface plasmon. The intermediate layer is interposed between the first metal layer and the second metal layer. Each of the first metal layer, the second metal layer and the intermediate layer has an end located in the front end face. Each of the first and second metal layers is formed of a metal material. The intermediate layer is formed of a material higher in Vickers hardness than the metal material used to form the first metal layer and the metal material used to form the second metal layer.
