Abstract
A method and system provide a near-field transducer (NFT) for an energy assisted magnetic recording (EAMR) transducer. The method and system include forming an NFT having a disk and a pin. A dielectric layer that substantially covers the NFT is deposited. A portion of the dielectric layer is removed such that the dielectric layer has an aperture therein. The aperture exposes the pin of the NFT. The EAMR transducer is annealed at a temperature greater than the expected operating temperature of the EAMR transducer.
