Abstract:
A magnetic recording head comprises a write pole tip adjacent to an air bearing surface and a return pole. In addition, a near field transducer is positioned adjacent the write pole in order to produce near field radiation to heat a portion of a recording medium to facilitate switching by the magnetic write pole. The near field transducer is a reverse optical near field transducer with internal bevel structures that enhance the magnetic write field intensity.
