Abstract:
A magnetic recording head consists of a write pole and a near field transducer close to the write pole that focuses light energy to a focal point. A near field transducer is positioned to receive light energy from a waveguide. The near field transducer comprises an energy-receiving end and an energy-radiating end. The energy-receiving end is located near the focal point of the waveguide and the energy-radiating end is shaped such that it is narrower closer to the write pole and wider farther from the write pole.
