ABSTRACT:
Improved flexible disk pack magnetic storage systems and associated elements are illustrated as adapted for end-wise pneumatic partitioning and indicate, among other features, the use of "rim means" in the gap between adjacent flexible disks to better isolate the axial pressurized air streams from non-selected gaps and also to provide a reference surface for registration of the disks in the course of compressing the stack together.
