Abstract
A method and system provides an EAMR transducer. The transducer is coupled with a laser for providing energy and has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The EAMR transducer includes a composite near field transducer (NFT), a write pole and at least one coil for energizing the write pole. The write pole is configured to write to a region of the media. The composite NFT is for focusing the energy onto the region of the media. The composite NFT includes at least one metal and at least one insulator therein.
