Partition of high performance floppy pack and associated means

摘要

Improved flexible disk pack magnetic storage systems and associated sub-assemblies and media are illustrated as combined with improved partition means in the embodiments, these involving a pack of flexible magnetic according disks stacked for co-rotation at high rpm on a manipulator assembly which includes a pneumatic separator-hub as the partitioner, being adapted to be shifted axially along the disk array so as to direct an air jet between selected disks and thereby selectable split the stack for entry of a transducer assembly.
