Thermally-assisted magnetic recording head having inclined main magnetic pole and core

摘要

A thermally-assisted magnetic recording head includes a main pole, a waveguide, and a plasmon generator. The waveguide includes a core and a cladding. The main pole and the core are located on the same side in the direction of travel of a recording medium relative to the plasmon generator. The main pole has a first end face located in the medium facing surface, and a second end face opposite to the first end face. The core has a front end face opposed to the second end face of the main pole. The cladding includes an interposition section interposed between the front end face of the core and the second end face of the main pole. The front end face of the core and the second end face of the main pole are inclined with respect to the medium facing surface.
