    摘要： A method and system for providing an EAMR transducer is described. The EAMR transducer has an ABS and is coupled with a laser. The EAMR transducer includes a write pole, coil(s), and an energy delivery device. The write pole magnetically writes to the media. The coil(s) energize the write pole. The energy delivery device is optically coupled with the laser and includes a top distal from the ABS, a bottom proximate to the ABS, a first side, and a second side opposite to the first side. The first side has a first apex angle from a normal to the ABS and is reflective. The second side has a second apex angle from the normal and is reflective. The first and second apex angles are each at least three and not more than twenty-five degrees. The first and second sides converge such that the top is wider than the bottom.

    摘要： 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.

    摘要： An energy assisted magnetic recording (EAMR) head for writing to a recording media is disclosed. The EAMR head includes a write pole for providing a magnetic field for writing to the recording media; and a near field transducer disposed adjacent to the write pole and comprising a disk section and a pin section extending towards an air bearing surface (ABS) from the disk section. At least a portion of the pin section is electrically isolated from the write pole by an insulator material.
