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： The true roughness of highly granular perpendicular media is measured by forming an inverse replica of the surface of the media. The invention enables AFM measurements of granular media valley depth to more consistently predict the corrosion performance of the media. A liquid resist is used to first replicate the media topography and form the inverse replica. The narrow valleys in the original media are precisely modeled as sharp peaks on the replica. The height of the peaks are readily measured with an AFM tip. The resulting image is a negative of the original surface.

摘要： Oxygen scavenger for use in a hard disk drive. The oxygen scavenger removes oxygen from an interior of a hard disk drive to prevent corrosion of corrodible materials in magnetic media or magnetic heads. The oxygen scavenger is incorporated into a film so that it uses a limited physical space within an interior of the hard disk drive. The hard disk drive is either permeable to the outside environment or sealed so that gases from the outside environment are unable to enter the interior of the hard disk drive.

摘要： Lubricant with non-terminal functional groups. The location of the functional groups minimizes free chain length and molecular weight of a lubricant while simultaneously maximizing evaporation temperature. The locations of the functional groups to the backbone of the molecule of the lubricant allows for shorter lengths of free backbone length between functional groups attached to a lubricated surface. The lubricant lubricates mechanical devices including hard disk drives. The lubricant can also be added to media or other mechanical parts in conjunction with other lubricants.

摘要： A method is presented for measuring the height of an air-bearing separating a flying component from a rotating surface using physical deformation of a small amount of material deposited on the surface. One embodiment of the invention is a method of measuring the fly-height of a slider using physical deformation of material deposited on the disk. Small amounts of the deformable material such as a viscoelastic lubricant are placed on a limited area of the disk so that the slider can otherwise fly normally. The slider's fly-height is established over the unaltered portion of the disk, then the slider impacts the deformable material. This process results in the deformable material being flattened or removed above the fly-height of the slider. The height of the remaining material is then measurable as the fly-height.

摘要： A method of polishing workpieces includes final tape polishing (FTP) a media disk by rotating the media disk; applying a liquid that is substantially pure to the media disk adjacent to an FTP tape; applying the FTP tape to the media disk at a pad load to polish the media disk, such that the liquid acts as a transient lubricant between the media disk and the FTP tape; and completing FTP. The FTP process is completely independent of the final disk lubricant, such that the final disk lubricant may be applied before or after FTP.
