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. According to certain embodiments, a flexible interdisk wiper is positioned between the disks and aids in stabilization thereof. In other embodiments, top and bottom disk wipers are also included.
