| 发明名称 | Anti-reflection waveguide for heat-assisted magnetic recording | ||
| 摘要 | A system, according to one embodiment, includes a magnetic head having: a near field transducer, an optical waveguide for illumination of the near field transducer, and an anti-reflection block positioned along the optical waveguide farther from a media facing side of the magnetic head than the near field transducer. The anti-reflection block is positioned a distance from the near field transducer to destructively interfere with light reflected away from the near field transducer. Other systems, methods, and computer program products are described in additional embodiments. | ||
