A method for manufacturing a magnetic disk is provided that includes the steps: forming a layer of a lubricant material on a surface of a magnetic storage medium, the layer of lubricant material also being located on an interior and/or exterior edge of the medium; and removing at least some of the lubricant material from the edgeof the medium.

Disk burnishing device

Various methods and apparatus for simultaneously cleaning two single-sided hard memory disks is provided. The two disks are placed in concentric contact merge orientation such that the outwardly facing surface of each disk, which has memory storage capabilities, may be simultaneously cleaned by equipment designed to clean one double-sided disk. Conversely, no effort is expended in cleaning the abutting inactive surfaces of the disks.

Apparatus for simultaneous two-disk scrubbing and washing

Various apparatus and methods are provided for positioning and handling hard memory disks. A disk carrier is provided with adjustably positionable side wall inserts. The inserts or panels may be moved between a plurality of positions to accommodate disks of different diameters. The inserts may also be substituted to accommodate disks of different thickness or different orientations, such as pairs of disks in gap merge orientation or contact merge orientation.

Cassette for holding disks of different diameters

A method for manufacturing a magnetic disk is provided that includes the steps:

Magnetic disk with uniform lubricant thickness distribution

Various apparatus and methods are provided for positioning and handling single-sided hard memory disks. A disk carrier is provided with ribs formed on the inside surface of opposing side walls. The ribs form disk receiving grooves or channels. The ribs further comprise an alternating pattern of large and small ribs. The large ribs separate pairs of disks from other pairs, the small ribs separate and maintain spacing of the two disks comprising each pair of disks.

Method for manufacturing single-sided hard memory disks

Various methods and apparatus for handling a plurality of disks and repositioning them into pairs is provided. In one embodiment, a nest is configured to hold a cassette and includes a nest. The nest includes a curved surface with ribs or teeth extending therefrom which define a row of grooves. The grooves are dimensioned to hold a pair of disks in concentric contact merge orientation and the teeth facilitate movement of pairs of disks into the grooves.

Automated merge nest for pairs of magnetic storage disks

Various methods and apparatus for simultaneously texturing two single-sided hard memory disks is provided. The two disks are placed in a concentric contact merge orientation such that the outwardly facing surface of each disk may be simultaneously subjected to texturing by equipment designed to texture one double-sided disk.

Method for simultaneous two-disk texturing

Various apparatus and methods are provided for lubricating hard memory disks. A mandrel is provided in one embodiment with three rows of teeth and provides a stable, three-point engagement with the inside edge of the disks at the center aperture. When removing disks from a cassette, the mandrel preferably places a uniform space between the disks. In a second embodiment, the mandrel may be used to lubricate single-sided hard memory disks. The single-sided hard memory disk may be positioned on the mandrel in pairs in a gap merge orientation, or equally spaced apart.
