    摘要： A thin-film magnetic head is constructed such that a main magnetic pole layer, a write shield layer, a gap layer, and a thin-film coil are laminated on a substrate. The thin-film magnetic head has a leading shield part opposing the main magnetic pole layer on the substrate side of the main magnetic pole layer, a substrate side shield part has contact with the leading shield part. The thin-film coil has a substrate side coil layer between the main magnetic pole layer and substrate. The spaces to the substrate about a leading lower end face of the leading shield part, a shield upper end face of the substrate side shield part, and coil upper end face of the substrate side coil layer are formed to be equal to each other. The depth of the leading shield part is formed to be smaller than the depth of the substrate side shield part.

    摘要： A plasmon generator configured to excite a surface plasmon based on light includes a first portion formed of a first metal material and a second portion formed of a second metal material different from the first metal material. The plasmon generator has a front end face. The front end face includes a near-field light generating part that generates near-field light based on the surface plasmon. The second portion includes an end face located in the front end face. The second metal material satisfies at least one of the following requirements: a lower ionization tendency than that of the first metal material; a lower electrical conductivity than that of the first metal material; and a higher Vickers hardness than that of the first metal material.

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 magnetic head includes a medium facing surface, a read head unit, a write head unit, and a protrusion device. The protrusion device causes part of the medium facing surface to protrude toward a recording medium. The read head unit has a first end face located in the medium facing surface and includes a first contact sensor for detecting contact of the first end face with the recording medium. The write head unit has a second end face located in the medium facing surface and includes a second contact sensor for detecting contact of the second end face with the recording medium. The first end face and the second end face are located at positions different from each other in a direction of travel of the recording medium.
