摘要：
A thermally-assisted magnetic recording head includes a main pole, a waveguide, a plasmon generator, and a heat sink. The heat sink includes a first metal layer, a second metal layer, and an intermediate layer. The intermediate layer is interposed between the first metal layer and the second metal layer. Each of the first and second metal layers is formed of a metal material. The intermediate layer is formed of a material that is higher in Vickers hardness than the metal material used to form the first metal layer and the metal material used to form the second metal layer.
