Abstract:
A heat-assisted magnetic recording head includes a write pole tip that extends to a media-facing surface and a heat sink that is thermally coupled to a side of the write pole tip. A surface plasmonic plate is in contact with a side of the heat sink that faces away from the write pole and is recessed from, the media-facing surface. A nanorod extends from a surface of the surface plasmonic plate and towards the media-facing surface.
