    摘要： Cleaning or polishing magnetic recording media (MRM) may comprise mounting and rotating the MRM on a spindle; circulating a tape adjacent to a surface of the MRM; and applying an electrostatic (ES) voltage to the tape and attracting particles located on the MRM to the tape. The ES voltage may apply an ES load to the tape to force the tape into contact with the surface of the MRM. No mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM. Additionally, a mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM.

    摘要： A method for manufacturing a magnetic media having an extremely thin lubricant layer on a magnetic media. The thin lubricant layer decreases magnetic spacing to maximize magnetic performance of the magnetic data recording system. The lubricant layer is formed by first depositing a lubricant that includes two different lubricant materials, one bonded and the other non-bonded. After lubricant deposition a burnishing process can be performed, with the lubricant being thick enough for effective burnishing. Then, the disk is exposed to a solvent vapor, which removes most of the lubricant leaving only a very thin layer of the bonded lubricant material.

    摘要： An apparatus, system, and method are disclosed for guided growth of patterned media using monodisperse nanospheres. The apparatus includes nanoscale features extending from a substrate. The nanoscale features may be formed using electron-beam lithography and have a non-uniform cap. A spherical cap is formed on the non-uniform cap by hydrolysis and precipitation of monodisperse nanospheres on an immobilized nucleation site, the immobilized nucleation site attached with one end of the nanoscale feature. The system includes the apparatus and further includes monodisperse nanospheres formed of silicon dioxide spheres. The method includes providing a substrate, etching at least one nanoscale feature extending from the substrate, the feature formed using electron-beam lithography and having a non-uniform cap, forming an immobilized nucleation site, and forming a spherical cap by hydrolysis and precipitation of monodisperse nanospheres on the immobilized nucleation site, the immobilized nucleation site attached with one end of the nanoscale feature.

    摘要： A method for planarizing a magnetic recording disk that has surface features of elevated lands and recessed grooves includes forming two coatings of cured perfluorinated polyether (PFPE) polymers over the surface features. The disk may have a protective carbon overcoat with a surface that replicates the topography of lands and grooves. A liquid functionalized-PFPE is applied over the disk surface and then cured to form a first coating with the functionalized end groups bonding to the carbon overcoat. A liquid non-functionalized-PFPE polymer is then applied over the functionalized-PFPE coating and cured to form a second coating. The combined coatings substantially planarize the disk surface so that there is minimal recession between the top of the coating over the lands and the top of the coating over the grooves.

    摘要： A batch vapor deposition process for applying adhesion promoter during manufacturing of nanoimprinted discrete track media and bit-patterned media, and mono-molecular layer lubricant on magnetic recording media are disclosed. The adhesion promoter is simultaneously coated on both sides of numerous disk substrates, and minimal solution is wasted. In another step, the lubricant is applied at a uniform thickness that is on the order of a single molecular layer. The lubricant is also applied on the entire disk surfaces while processing multiple disks at a time. Batch processing increases throughput, and vapor lubricant reduces costs compared to conventional techniques. Limited air exposure controls bonding and monolayer adsorption guarantees uniformity.
