| 发明名称 | Thermally-assisted magnetic recording head | ||
| 摘要 | Thermally-assisted magnetic recording head, includes: a magnetic pole having an end exposed on an air-bearing surface; a waveguide; a plasmon generator having a first and second region, first region extending backward from the air-bearing surface to a first position, second region being coupled with the first region at the first position, extending backward from first position, and having a width in a track-width direction, and width in the track-width direction of second region being larger than a width in the track-width direction of first region; an adhesion layer having an end exposed on the air-bearing surface and a first adhesion region, the first adhesion region being in close contact with an end face in the track-width direction of first region; and a cladding layer located around plasmon generator and adhesion layer. Adhesion force between adhesion layer and plasmon generator is greater than adhesion force between cladding layer and plasmon generator. | ||
