Abstract
An apparatus comprises a writer, a near-field transducer (NFT), a channel waveguide proximate the NFT, a dielectric layer between the NFT and waveguide, and a plurality of heat sinks. A first heat sink comprises a gap and contacts the NFT and the writer. A second heat sink extends across the gap of the first heat sink and between the NFT and a heat reservoir component, such as a return pole of the writer. The channel waveguide may contact the second heat sink, such as by encompassing a peripheral portion of the second heat sink. The second heat sink may have at least an outer surface comprising a plasmonic material, and may be configured to enhance plasmonic excitation of the NFT.
