成形されたエネルギー放射端部を含む近接場変換器を備えた装置

摘要

A magnetic recording head consists of a write pole (36) and a near field transducer close to the write pole (36) 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 (36) and wider farther from the write pole (36).
