Abstract
Abstract A disk package for memory disks and the like and including a top cover, a disk cassette, and a bottom cover where the top cover includes sides with hooks which engage about catches on the box, and the bottom cover includes a channel which frictionally engages to the bottom edges of the box. The disk cassette supports a plurality of memory disks through perimeter contact of a rounded side and separated by teeth. The top cover includes a plurality of fingers which extend downwardly from the top cover, the fingers movable with respect to each other for engaging each disk independently of each other. The disks are separated by teeth having a rounded profile and a flat portion therebetween for perimeter contact with the disks, the teeth being longitudinal in length and running about the rounded sides and sides of the box.
