    • A thermally-assisted recording (TAR) head for recording data in data tracks of a TAR disk is supported on an air-bearing slider and includes the magnetic write pole, a near-field transducer (NFT), an optical waveguide that directs laser light to the NFT, and an electrically conductive layer between and in contact with the NFT and the write pole. The NFT has an output tip having a generally triangularly-shaped end at the slider's air-baring surface (ABS). The electrically conductive layer is located between the NFT and the write pole and contacts both the NFT output tip and the write pole. The electrically conductive layer has a contact edge that is generally parallel with the ABS but recessed from the NFT output tip end and a cross-track width greater than the cross-track width of the NFT output tip end.
    • 用于在TAR盘的数据轨道中记录数据的热辅助记录(TAR)头被支撑在空气轴承滑块上,并且包括磁性写入极,近场换能器(NFT),引导激光的光波导 NFT和在NFT和写入极之间接触的导电层。 NFT具有在滑块的空气表面(ABS)处具有大致三角形的端部的输出端头。 导电层位于NFT和写极之间,并接触NFT输出端和写极。 导电层具有大致平行于ABS但是从NFT输出端部凹陷的接触边缘,并且跨轨道宽度大于NFT输出端部的横向轨道宽度。

    • 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.
