Abstract:
1. A device, comprising: a light source; a near-field light transducer comprising an electroconductive scattering body configured for generating near-field light when irradiated by light provided by the light source, wherein the near-field light transducer comprises a triangular shape at a media-facing surface thereof having three apexes including a trailing-side apex positioned on a trailing side of the near-field light transducer; a main pole configured for writing data to a magnetic medium, the main pole being positioned in a down-track direction from the near-field light transducer; a first material positioned near the trailing-side apex of the near-field light transducer; and a second material positioned near other apexes of the near-field light transducer, wherein the near-field light transducer is configured to assist the main pole in writing data to the magnetic medium by production of the near-field light, and wherein the first material is more difficult to etch than the second material.
