    摘要: A return path section includes first and second yoke portions and first, second and third columnar portions. The first and second yoke portions and the first columnar portion are located on the front side in the direction of travel of a recording medium relative to a waveguide core. The second and third columnar portions are located on opposite sides of a plasmon generator and connected to a shield. The first yoke portion connects a main pole to the first columnar portion. The second yoke portion connects the first columnar portion to the second and third columnar portions. A coil is wound around the first columnar portion. A heater and an expansion layer are located on the rear side in the direction of travel of the recording medium relative to the core.

    摘要: A plasmon generator has a front end face located in a medium facing surface of a magnetic head. The plasmon generator includes a first portion formed of a first metal material and a second portion formed of a second metal material. The first portion has an inclined surface facing toward the front end face. The second portion is located between the inclined surface and the front end face, and includes a first end face located in the front end face and a second end face in contact with the inclined surface. The second metal material is higher in Vickers hardness than the first metal material. The first portion has a plasmon exciting part. The front end face generates near-field light.

    摘要: A magnetic head includes a coil, a main pole, a write shield, a gap section, and a return path section. The main pole has a top surface including an inclined portion and a flat portion. The coil includes a specific coil element. The specific coil element has a front end portion, and an inclined surface contiguous with the front end portion. The write shield includes a top shield layer located on the front side in the direction of travel of a recording medium relative to the main pole, and located closer to a medium facing surface than the specific coil element. The top shield layer is located on the rear side in the direction of travel of the recording medium relative to an imaginary plane including the inclined surface of the specific coil element.

    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 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.
