ABSTRACT:
A multi-disk floppy disk pack; also shown in an embodiment particularly adapted for co-action with disk drive apparatus for handling flexible disk packs, and including a partitioning diverting shield, flexure-bar mounted transducer head under the shield, along with disk-cleaner/stabilizer means--these being shown arrayed as a double-opposed transducer assembly adapted to be so manipulated into the pack as to double-partition the pack away from a selected disk on which opposed dual-transducing manipulations may be effected. Such stabilizer means operates up-stream of the head to reduce disk-flutter, etc.
