Abstract
Embodiments of the present invention are directed toward a bi-layer spacer structure and related fabrication processes for improving an interface between a near-field transducer (NFT) and a spacer on an optical waveguide core for an energy assisted magnetic recording (EAMR) system. The embodiments provide a solution for improving the adhesion between the NFT and the spacer.
