Abstract
A near field transducer (NFT) for use in an energy assisted magnetic recording (EAMR) head and configured to direct energy to a recording media is disclosed. The NFT comprises a disk section; and a pin section extending towards an air bearing surface (ABS) from the disk section. The pin section has a proximal end adjoining the disk section and a distal end opposite to the proximal end and facing the ABS, wherein at least the distal end of the pin section has a non- rectangular cross section in a plane parallel to the ABS.
