Abstract
A disk cartridge assembly includes a rotatable magnetic disk enclosed within a rectangular cartridge. Attached to the top and bottom covers of the cartridge are a plurality of leaf springs which urge the top and bottom sections toward and against one another. Resilient cloth liners are mounted to the inside surfaces of the top and bottom covers. As the leaf springs urge these sections toward one another, the liners engage the disk surface to prevent the disk from moving freely within the cartridge. The leaf springs are flexible in the axial direction but rigid in the radial direction, thus to maintain the top and bottom sections in alignment with one another.
