Thermally-assisted magnetic recording head having a plasmon generator |
摘要 |
A thermally-assisted magnetic recording head includes a waveguide having a core and a cladding, and a plasmon generator. The core has an evanescent light generating surface. The plasmon generator has a plasmon exciting part opposed to the evanescent light generating surface. Assuming a virtual straight line that passes internally through the core and that is parallel to the direction of travel of light propagating through the core, at least part of the evanescent light generating surface and at least part of the plasmon exciting part are both inclined relative to the virtual straight line such that the distance from the virtual straight line decreases with increasing proximity to the medium facing surface. |
