Abstract:
A thermally-assisted magnetic recording head includes a main pole and a plasmon generator. The plasmon generator includes a first material portion and a second material portion formed of different materials. The first material portion is located away from the medium facing surface. The second material portion includes a near-field light generating surface. The main pole has a front end face including a first end face portion and a second end face portion. The near-field light generating surface, the first end face portion and the second end face portion are arranged in this order along the direction of travel of a recording medium.
