Abstract
An apparatus includes a waveguide having a core layer and an end adjacent to an air bearing surface, first and second poles magnetically coupled to each other and positioned on opposite sides of the waveguide, wherein the first pole includes a first portion spaced from the waveguide and a second portion extending from the first portion toward the air bearing surface, with the second portion being structured such that an end of the second portion is closer to the core layer of the waveguide than the first portion, and a heat sink positioned adjacent to the second portion of the first pole.

An apparatus comprising:
- first and second poles magnetically coupled to each other and positioned on opposite sides of a waveguide;
- and
- a near-field transducer (NFT) adjacent to the waveguide and a heat sink positioned adjacent the NFT and capable of cooling the NFT.
An apparatus comprising:
- first and second poles magnetically coupled to each other and positioned on opposite sides of a waveguide;
- a near-field transducer positioned adjacent to the waveguide;
