ABSTRACT:
The disclosed embodiments are characterized by flexible disk packs and related storage apparatus characterized by disks with a circumferential tab section adapted to be engaged by associated partition wedge means; in one form each disk is identical and the disks are stacked so that each tab occupies a unique angular position in the stack -- this facilitating selective engagement of any tab by the wedge so as to effect pack-partition and exposure of a "selected" disk surface for transducer access.
