Abstract:
1. A thermally-assisted magnetic recording head, comprising: a magnetic pole having an end exposed on an air-bearing surface; a waveguide; a plasmon generator having a first region and a second region, the first region extending backward from the air-bearing surface to a first position, the second region being coupled with the first region at the first position, extending backward from the first position, and having a width in a track-width direction, and the width in the track-width direction of the second region being larger than a width in the track-width direction of the 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 the first region; and a cladding layer located around the plasmon generator and the adhesion layer, wherein adhesion force between the adhesion layer and the plasmon generator is greater than adhesion force between the cladding layer and the plasmon generator.
