摘要： A thermally-assisted magnetic recording head includes a main pole and a plasmon generator. The main pole has a front end face located in the medium facing surface. The plasmon generator has a near-field light generating surface located in the medium facing surface. The front end face of the main pole includes a first end face portion and a second end face portion. The second end face portion is located farther from the near-field light generating surface than is the first end face portion, and is greater than the first end face portion in width in the track width direction. The first end face portion and the near-field light generating surface are equal in width.
