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.
