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.
