ABSTRACT:
Improved flexible disk pack magnetic storage systems and associated elements are illustrated as adapted for end-wise pneumatic partitioning of a pack of flexible record disks and indicate, among other features, the use of "isolation packs" flanking the record pack to better isolate it, and especially the outer record-disks, from an outer pair of end-plates between which the isolation packs are disposed, the size and composition of each isolation pack being optimized and the gaps between isolation disks preferably coupled, pneumatically, to prescribed record-gaps and varied in height, with "large" isolation gaps coupled to "record-gaps" that are more difficult to partition.
