Abstract
A method and system provides a near-field transducer (NFT) for a heat assisted magnetic recording (HAMR) transducer. The method and system include forming the disk of the NFT and forming the pin of the NFT. The disk is formed from a first material. The pin is formed from a second material different from the first material. The pin contacts the disk. At least a portion of the pin is between the disk and an air-bearing surface (ABS) location.
