STRUCTURE POSITIONED BETWEEN MAGNETIC POLE AND NEAR-FIELD TRANSDUCER |
| 摘要 |
An apparatus includes a waveguide, a magnetic pole, and a near-field transducer. The near field transducer is positioned at or near a media-facing surface. The near-field transducer is operatively coupled to the waveguide. The near-field transducer includes an enlarged region. The near-field transducer also includes a peg region extending from the enlarged region towards the media-facing surface. The peg region is separated from the magnetic pole. The near-field transducer also includes a structure positioned between the magnetic pole and the peg region. The structure is separated from the peg region by a gap. The structure extends from the enlarged region towards the media-facing surface. The structure is configured to extend generation of surface plasmons toward the magnetic pole. |

1. An apparatus comprising:
a waveguide; a magnetic pole; and a near-field transducer positioned at or near a media-facing surface and operatively coupled to the waveguide, the near-field transducer comprising: an enlarged region; a peg region extending from the enlarged region towards the media-facing surface, the peg region separated from the magnetic pole; and a structure positioned between the magnetic pole and the peg region and separated from the peg region by a gap, the structure extending from the enlarged region towards the media-facing surface and configured to extend generation of surface plasmons toward the magnetic pole. |
