Abstract: A hub for a storage package for storing a recording medium includes a base member, an uninterrupted deformable, generally domed portion, and at least one gripping formation extending from the generally domed portion. The gripping formation is positioned to extend through a hole in the recording medium and engage the inner edge of the recording medium as the medium is placed onto the hub. The generally domed portion and the gripping formation are directly joined at a location disposed above the recording medium when the recording medium is placed onto the hub. Deformation of the generally domed portion in a direction transverse to the base member directly causes the gripping formation to retract radially inward to allow removal of the recording medium.
