ABSTRACT:
A flexible disk pack having a pair of floppy end plates. The end plates are adapted to assume a Delta or tapered shape when they are rotated with the record pack. Each of the end plates is formed of at least two stacks of contiguous flexible disks separated by wedge spacers. The thickness and mass of the outer stack of each end plate is determined by the stiffness desired while the thickness and mass of the inner stack is selected to cause it to bend smoothly toward the outer stack allowing for pneumatic stability during partitioning.
