Abstract

Embodiments of the present invention are directed to a recording head for energy assisted magnetic recording. The recording head includes a near-field transducer (NFT) having a preselected shape and a surface, a writing pole on the NFT, and a non-metal heat dissipator positioned between the NFT surface and the writing pole. The non-metal heat dissipator includes a first portion in contact with the NFT surface, the first portion extending beyond an edge of the NFT surface in a first direction substantially perpendicular to an air bearing surface (ABS) and parallel to the NFT surface.
