A pack of flexible magnetic recording disks may be partitioned "end- wise". In one embodiment 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 to the pack to register with a selected one of these bores. <IMAGE> |
