发明名称 Thermally-assisted recording (TAR) head with waveguide having tapered region coupled to near-field transducer
摘要 A thermally-assisted recording (TAR) head for recording data in data tracks of a TAR disk has an air-bearing slider that supports a near-field transducer (NFT) and an optical waveguide that directs laser light to the NFT. The NFT has an output end at the slider's air-bearing surface (ABS) located between the write pole and the optical waveguide in the along-the-track direction. The NFT output end is generally triangularly shaped with an apex facing the write pole and a back edge wider than the apex in the cross-track axis direction facing the waveguide. The surface of the waveguide facing the NFT back edge is tapered, with a width in the cross-track axis direction at a region recessed from the ABS and a smaller width in the cross-track axis direction at an end near the ABS.
