    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 magnetic recording system, such as a magnetic recording disk drive, uses a patterned perpendicular magnetic recording medium where each magnetic block or island contains a stack of individual magnetic cells to provide multilevel recording. Each cell in an island is formed of a material or set of materials to provide the cell with perpendicular magnetic anisotropy and is a single magnetic domain. Each cell is magnetically decoupled from the other cells in its island by nonmagnetic spacer layers. Thus each cell can have a magnetization (magnetic moment) in one of two directions (into or out of the plane of the layer making up the cell), and this magnetization is independent of the magnetization of the other cells in its island, This permits multiple magnetic levels or states to be recorded in each magnetic island.

    摘要： A magnetoresistive (MR) sensor can be shaped using ion beam irradiation and/or implantation through a mask introduced between a MR structure and an ion source. The mask covers selected portions of the MR structure to define the track width of the sensor. Ion irradiation and/or implantation reduces the magnetoresistance of the unmasked portions while leaving the masked portion substantially unaltered. The mask can be a photoresist mask, an electron beam resist mask, or a stencil mask. Alternatively the mask may be part of a projection ion beam system. Track width resolution is determined at the mask production step. The edges of the sensor can be defined by a highly collimated ion beam producing an extremely straight transition edge, which reduces sensor noise and improves sensor track width control. Improved hard bias layers that directly abut the sensor may be used to achieve a suitable stability. A variety of longitudinal bias schemes are compatible with ion beam patterning.

    摘要： A patterned magnetic recording disk, i.e., a disk with discrete magnetically recordable regions that can function as discrete magnetic bits, is formed by ion irradiating a continuous magnetic film of a chemically-ordered alloy having a tetragonal crystalline structure through a patterned non-contact mask. The ions cause disordering in the film and produce regions in the film that have no magnetocrystalline anisotropy. The regions of the film not impacted by the ions retain their chemical ordering and magnetocrystalline anisotropy and thus serve as the discrete magnetic regions that can be recorded as individual magnetic bits. The chemically-ordered alloy is preferably Co (or Fe) and Pt (or Pd) with the c-axis of the tetragonal crystalline film oriented at an angle less than 45 degrees relative to the plane of the film, so that after patterning the discrete magnetic regions can be recorded by horizontal magnetic recording.
