Abstract
Improved disk pack media for data storage is illustrated as comprising a pack of flexible magnetic recording disks which may be partitioned 'end-wise'. In one embodiment the disks are perforated for partitioning and also stacked in a different respective rotational orientation to facilitate end-wise partitioning. The disks are hole-encoded and either cut in different hole patterns, or else cut in a common hole pattern and stacked to dispose each in a unique rotational 'misregistration' relative to all others--the result being to generate sets of 'partition bores' permitting associated automatic apparatus to selectively partition the pack and expose any desired disk-side for operation thereon. In another embodiment the disks are stacked between apertured spacers about a hollow spindle, the spacers and disks being partition-apertured and stacked to generate a set of partition bores. These bores cooperate with selectably rotatable gas jet means co-rotated on the spindle and adjustably rotated relative the pack to register with a selected one of these bores.
