Abstract: A device for the storage of cassettes, specifically CD-cassettes, formed of a wall assembly of a plurality of identical bar elements (1) with plug and bores at their planar end areas (5) and pin for connecting the bar elements in a staggered manner having gaps. The bar elements (1) form in a preferred kind at a rack-like arrangement of respective two pairs of bar elements (1) transversely over two bar elements (1) located below and at a stacking above each other in several layers a tower-like rack (10) with slide-in compartments (11) formed by the gaps for one respective cassette (9) between two respective bar elements (1) located above each other. Each bar element includes at the steplike stepped inner longitudinal side (6) at the center an abutment (7) formed by the step for limiting the slide-in path of the cassettes to be slid in from the opposite side. By way of the bar elements any arbitrary frame height for an optimal utilization of given space condition can be produced.
