Abstract
A device and process for stabilizing two coaxially joined flexible magnetic disks is disclosed. Two or more flexible magnetic disks are coaxially joined by a coaxially located spacer. One of the disks is juxtaposed to and rotated against a flat stable Bernoulli surface. A second disk spaced by the spacer from the first disk contains centrally located perforations into which air can flow. When the disks are rotated at high speed air flows into the perforations and radially out from between the disks, thus forming an air cushion or air bearing between the disks. The apparatus and process thus provides two floppy disks stabilized by a single Bernoulli surface.
