    摘要： A diffraction aberration corrector formed by the multipole of the solenoid coil ring and having a function of adjusting the degree of orthogonality or axial shift of the vector potential with respect to the beam axis. In order to cause a phase difference, the diffraction aberration corrector that induces a vector potential, which is perpendicular to the beam axis and has a symmetrical distribution within the orthogonal plane with respect to the beam axis, is provided near the objective aperture and the objective lens. A diffracted wave traveling in a state of being inclined from the beam axis passes through the ring of the magnetic flux. Since the phase difference within the beam diameter is increased by the Aharonov-Bohm effect due to the vector potential, the intensity of the electron beam on the sample is suppressed.

    摘要： A magnetic head includes a magnetic structure incorporating a write shield. The magnetic structure is formed to include a first magnetic layer, a second magnetic layer stacked on the first magnetic layer, and a seed layer. The first magnetic layer has a front end face located in the medium facing surface and a top surface. The second magnetic layer has a front end face located in the medium facing surface and a bottom surface. The top surface of the first magnetic layer includes a first region including an end located in the medium facing surface and a second region farther from the medium facing surface than the first region. The seed layer is not present on the first region of the top surface of the first magnetic layer but is present on the second region.

    摘要： A plasmon generator has a front end face, a first metal layer, a second meta-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.

    摘要： A main pole has an end face located in a medium facing surface, and first through sixth side surfaces. The first and third side surfaces are connected to the end face of the main pole. The second and fourth side surfaces are located farther from the medium facing surface than are the first and third side surfaces. The fifth side surface connects the first side surface to the second side surface. The sixth side surface connects the third side surface to the fourth side surface. The distance between the first side surface and the third side surface decreases with increasing proximity to the top surface of the substrate. The shape of the first side surface is defined by a first side shield. The shape of the third side surface is defined by a second side shield.

    摘要： A thermally-assisted magnetic recording head includes a coil, a main pole, a return path section, a waveguide, and a plasmon generator. The waveguide includes a core and a cladding. The return path section includes: first and second columnar portions located on opposite sides of the core in the track width direction; a coupling portion coupling the first and second columnar portions to each other; and a third columnar portion connected to the coupling portion. The third columnar portion is smaller than the coupling portion in width in the track width direction. The coil includes a winding portion wound around the third columnar portion.
