    Abstract: An apparatus (e.g., a heat assisted magnetic recording write heat) includes a magnetic write pole having a tip portion proximate a media-facing surface. A near-field transducer is proximate the tip portion of the magnetic write pole. A first heat sink portion is provided along a first side of the tip portion that faces away from the near field transducer. The first heat sink portion includes a highly reflective, thermally conductive metal and is spaced away from the media facing surface. A second heat sink portion is provided along the first side of the tip portion between the media facing surface and the first heat sink portion. The second heat sink portion includes a relatively hard material.
