Abstract
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.
Claims21
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;
- 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, and
- wherein the disk section is separated from the write pole by a heat sink layer and at least a portion of the pin section is separated from the write pole by an insulating layer.
