Abstract: A heat-assisted magnetic recording (HAMR) air-bearing slider has an optically-transparent protective film over the near-field transducer (NFT) to protect the NFT from excessive heat caused by the accumulation of carbonaceous material on the slider's overcoat. The NFT is thus separated from the overcoat by the protective film. The protective film does not cover the write pole end, which is covered only by the overcoat, so there is no spacing loss between the write pole end and the recording layer on the disk. In one embodiment the protective film is coplanar with the recording-layer-facing surface of the slider and the overcoat covers both the protective film and the write pole end. In another embodiment the overcoat has a window that surrounds the protective film, with the protective film being substantially coplanar with the air-bearing surface (ABS) of the slider. In both embodiments the smooth topography of the slider's ABS is maintained.

Abstract: A slider for magnetic data recording in a thermally assisted recording system. The slider has a slider body and a magnetic recording head formed on a trailing edge of the slider body. A first terminal is formed on a trailing edge surface of the recording head, and a second terminal is formed on a backside surface both the magnetic recording head and the slider body so as to extend across both the magnetic recording head and the slider body. An electrically conductive lead formed within the magnetic recording head connects the first lead with the second lead.

Abstract: In one embodiment, a magnetic head slider includes a substrate, at least two elements (read element, write element, and/or heater element) positioned adjacent to the substrate, a resistance detection element positioned near the two elements, a pair of conductive terminals in an accessible position and coupled to each of the two elements, a protective film surrounding the two elements and the resistance detection element, a first and a second thin conductive wire extending from the resistance detection element and terminating at an edge of the protective film, a third thin conductive wire extending from one of the pair of conductive terminals for a first of the two elements and terminating at an edge of the protective film, and a fourth thin conductive wire extending from one of the pair of conductive terminals for a second of the two elements and terminating at an edge of the protective film.
