NEAR-FIELD TRANSDUCER WITH ROUNDED OR OBTUSE CORNERS |
| 摘要 |
Embodiments are directed to an apparatus having an air-bearing surface that is configured to interact with magnetic medium. The apparatus includes a waveguide and a plasmonic near-field transducer positioned at or near the air-bearing surface. The plasmonic near-field transducer is operatively coupled to the waveguide. The plasmonic near-field transducer includes an enlarged region and a peg region. The peg region extends from the enlarged region towards the air-bearing surface. The peg region has at least a portion of a periphery of its cross-sectional shape include curvature or at least one substantially obtuse angle. |
