    摘要： An apparatus and method for lapping and fabricating a read/write head is described. The lapping method includes performing a first lapping process on a structure having the read/write head fabricated therein. The first lapping process is for reducing a first resistive region. The first resistive region is located proximal to a surface of the structure. The first lapping process is for achieving a first lapping benchmark. The lapping method further includes performing a second lapping process on a second resistive region. The second lapping process laps at a rate lesser than the first lapping process. The second lapping process is for achieving a second lapping benchmark. The second resistive region is interposed between the first resistive region and the read/write head. The second resistive region has a different resistive value than the second resistive region.

    摘要： A process for forming a plurality of sliders for use in thermally-assisted recording (TAR) disk drives includes a wafer-level process for forming a plurality of aperture structures, and optionally abutting optical channels, on a wafer surface prior to cutting the wafer into individual sliders. The wafer has a generally planar surface arranged into a plurality of rectangularly-shaped regions. In each rectangular region a first metal layer is deposited on the wafer surface, followed by a layer of radiation-transmissive aperture material, which is then lithographically patterned to define the width of the aperture, the aperture width being parallel to the length of the rectangularly-shaped region. A second metal layer is deposited over the patterned layer of aperture material. The resulting structure is then lithographically patterned to define an aperture structure comprising aperture material surrounded by metal and having parallel radiation entrance and exit faces orthogonal to the wafer surface.

    摘要： A write head structure for use with thermally assisted recording is disclosed. Improved heat sinking is provided for removing thermal energy created by a ridge aperture near field light transducer. Metal films conduct heat away from the region near the ridge aperture to the high pressure air film at the ABS between the head and media. This heat is further dissipated by the media. The metal films have varying thickness to improve lateral conductivity and may be composed of Au combined with a harder metal such as Ru to improve wear characteristics at the ABS.
