Abstract

Perforations are used to reduce rotational surface stress in co-rotating floppy type storage disks arranged for co-rotation in deformable pack. A perforation design especially useful for this purpose is indicated in the drawing. Successive disks 1, 2 have relatively offset elongated perforations 1a, 2a as shown (2a dotted for schematic clarity), which allow for increased circulation of air between the disks with less confinement of the disk material in the spaces between perforations. As a result, there is less resistance to lateral motion influence which operates to increase lateral flexibility and reduce deformational stress.
