the invention involves durable and protective data storage disc cases . a case includes two portions that join to form an inner support at the center of a disc and an outer support surrounding the disc at its outer diameter . the inner and outer supports prevent the case from contacting , and possibly scratching , the data surface of a disc within the case , even when the case is subjected to a compressive force . furthermore , the case may secure a disc by holding the disc at its center using a spindle and by holding the outer edge , beyond the data surface , on a rim at the outer support . in this manner , a disc is centered on the spindle , and further constrained by the rim at its outer edge . this secures the disc when the halves of the case are closed and allows the disc to be freely removed once the case is opened .
