Abstract: A storage system for recording media such as cassettes for audio or video equipment or compact discs in its own original protective box which consists of lid and drawer elements capable of moving relative to each other. The boxes are stored in a holding space in a storage rack. The box can be introduced into or removed from the space for the storage and the insertion or removal of the medium in a closed `storage position` (I) or in an open `access position` (II). A holder to retain a protective box in the desired positions in the rack consists of connecting structure to retain the box in position relative to the holder. The holder interacts with the storage rack to prevent the holder and the protective box from being moved past the desired `access position` (II), and as to prevent unauthorized movement from the `storage position` of the holder.
