    • Provided is a structure of a heat assisted magnetic recording head gimbal assembly that allows common inexpensive TE-mode LDs to be utilized. The heat assisted magnetic recording head gimbal assembly comprises: a light source unit having a light emitting element mounted on a parabolic solid submount; a heat assisted magnetic recording head comprising a magnetic recording element, a read element, a near field transducer, and a waveguide for guiding light from the light emitting element into the near field transducer; a slider including the heat assisted magnetic recording head and which flies above a disk; and a suspension for supporting the slider. The light emitting element of the light source unit is an edge-emitting LD and the light source unit is arranged on the opposite side of an bearing surface of the slider such that the light emitting surface of the light emitting element faces the slider, apertures are created in the suspension, and the slider is connected to the suspension in a way that a part of the light source unit penetrates through the apertures of the suspension.

    • 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.
    • 用于在TAR盘的数据轨道中记录数据的热辅助记录(TAR)头具有支撑近场换能器(NFT)的空气轴承滑块和将激光引导到NFT的光波导。 NFT在沿着轨道方向位于写入极和光波导之间的滑块的空气轴承表面(ABS)处具有输出端。 NFT输出端通常是三角形的,其顶点面向写入极,并且后边缘比面向波导的横向轨道轴线方向上的顶点更宽。 面向NFT后边缘的波导表面是锥形的,其横向轴线方向的宽度在从ABS凹陷的区域和在靠近ABS的端部处的横向轨道轴线方向上的较小宽度。
