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.

Abstract translation: 磁记录头由靠近写入极的写极和近场传感器组成，将光能聚焦到焦点。 定位近场传感器以从波导接收光能。 近场换能器包括能量接收端和能量辐射端。 能量接收端位于波导的焦点附近，并且能量辐射端被成形为使得其更靠近写入极并且比写入极更远。
