Abstract
An energy assisted magnetic recording (EAMR) transducer having an air-bearing surface (ABS) is described. The EAMR transducer includes at least one near-field transducer (NFT) and an electronic lapping guide (ELG) substantially coplanar with a portion of the at least one film. In some aspects, the NFT includes a disk portion and a pin portion. The pin is between the disk portion and the ABS. The pin portion corresponds to a critical dimension of the NFT from an ABS location.
