Abstract:
1. An energy assisted magnetic recording (EAMR) head for writing to a recording media, the EAMR head comprising: a write pole for providing a magnetic field for writing to the recording media; at least one laser for providing energy to the recording media to assist the writing; and a near field transducer (NFT) disposed adjacent to the write pole and coupled with the at least one laser, the NFT configured to direct the energy to a corresponding thermal spot on the recording media, wherein the NFT comprises a disk section and a pin section extending towards an air bearing surface (ABS) from the disk section, the pin section having a proximal end adjoining the disk section and a distal end opposite to the proximal end and facing the ABS, and wherein the distal end of the pin section has a non-rectangular cross section in a plane parallel to the ABS and the proximal end of the pin section has a rectangular cross section in the plane parallel to the ABS.
