Abstract
A container casing exchangeably holding an optical disc that can be loaded on a disc drive device as it holds an optical disc. The container casing includes a casing main member having a disc housing section for holding the disc-shaped recording medium towards its major surface, an aperture for recording and/or reproducing the disc-shaped recording medium held in the disc housing section and a center opening for rotationally driving the disc-shaped recording medium held in the disc housing section. The casing main member rotatably carries a cover member for opening/closing the disc housing section and an opening/closure controlling members. These opening/closure controlling members are moved between the first position engaging with the cover member and the second position disengaged from the cover member to control the opening/closure of the cover member to enable opening/closure of the cover member to enable exchange of the optical disc while assuring the positively closed state of the disc housing section.
