Abstract
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.
