A storage case has a base and a lid parallel to the base. The base has a rigid base plate with a rigid support for a data disk that stores digital information. The base has a fastening zone arranged centrally on the base plate and connected to the base plate by springy radial sections. The fastening zone has a central rigid pressure element and tongues distributed about the pressure element for securing positively the data disk. The tongues have integral snap-on cams projecting past an edge of a central opening of the data disk resting on the support. The radial sections have inner ends connected directly to the pressure element. The tongues are connected by a bending location to the inner ends. The support is arranged directly about the radial sections so as to be proximal to the edge of the central disk opening.
