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.

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： The present invention generally relates to fabricating a bond pad for electrically connecting a laser diode to a slider and a TAR head in a HDD. The bond pad is deposited on a surface of the head that is perpendicular to the air bearing surface (ABS). The head is diced and lapped to expose the bond pad on a top surface of the head and mounted on a slider. The laser diode and a sub-mount may be coupled to the top surface of the slider—i.e., the surface opposite the ABS—by connecting to the bond pads. Specifically, both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads. Conductive bonding material is used to bond the laser diode and the sub-mount to the bond pads.

摘要： A thin film conductive line is formed between MR pads on an MR head for protecting an MR sensor from electrostatic discharge (ESD) during assembly steps between row level fabrication of the head and prior to merge of a head stack assembly with a disk stack assembly. The conductive line may have a reduced thickness delete pad. A laser beam having a fluence sufficient to sever the conductive line at the delete pad but insufficient to damage or cause debris from structure underlying or surrounding the conductive line is used to sever the conductive line. The method traverses minimum energy, short laser pulses at a high pulse rate across the line, the melted material withdrawing from the melted area and being heaped on top of adjacent portions of the delete pad by surface tension and the melted material cooling to room temperature before the next pulse so that there is no cumulative heating and therefore no damage to or debris from the underlying structure. The conductive material of the line is incrementally plowed to each side of a severed path by successive overlapping laser pulses so that when the series of laser pulses has traversed the width of the delete pad the conductive line has been severed.
