An improved disk cassette, particularly advantageous for the containment of data storage disks, having a plurality of adjacently disposed rib members, wherein each rib member has an improved cross-sectional profile such that engagement grooves defined therebetween have a dual angle configuration which maintain each disk in radial contact at four different areas along the chamfered periphery thereof to minimize particulation from forming within the disk cassette. More particularly, the improved disk cassette restricts the mobility of the disks and minimizes the amount of contact area between the disks and the disk cassette so as to collectively reduce the propensity for particulation. The improved disk cassette of the present invention is also streamlined in terms of the amount of material required for manufacture, thereby decreasing the cost of materials, the cycle time for curing, and overall cost of manufacture.

[ What is claimed is:] [1.] An improved disk cassette for carrying a plurality of disk-shaped articles comprising:a first end wall disposed opposite a second end wall;a first lateral support wall disposed opposite a second lateral support wall; anda disk containment portion disposed between said first and second end walls, said disk containment portion including opposing side walls, each of said opposing side walls including a plurality of rib members disposed in parallel relation along an interior surface of each of said opposing side walls, each of said plurality of rib members having an upper surface extending between a pair of lateral surfaces, each of said pair of lateral surfaces including a lower angular surface extending at a first predetermined angle, and an upper angular surface extending between said lower angular surface and said upper surface at a second predetermined angle, each of said opposing side walls further including a semi-cylindrical area having a first wall thickness and a straight upper area that tapers away from said semi-cylindrical area to a lesser wall thickness, said straight upper area having a plurality of buttress members on its interior to provide added support.
