Plasmon generator includes three metal layers for thermally-assisted magnetic recording
A plasmon generator has a front end face located in a medium facing surface of a magnetic head. The plasmon generator includes a first layer formed of a first metal material, a second layer formed of a second metal material, and a third layer formed of a third metal material. Each of the second and third layers has an end portion constituting part of the front end face. The first layer does not have any portion constituting part of the front end face. The first and second metal materials are higher in electrical conductivity than the third metal material. The third metal material is higher in Vickers hardness than the first and second metal materials. The first layer has a plasmon exciting part.
