Device ( 2 ) for storing, managing and/or retrieving data stored on data carriers, in particular on CD's, comprising a set of plates ( 1 ) with recesses ( 3 ) for data carriers, situated one above another. The adjoining plates ( 1 ) are connected by shaped key joints ( 7,8 ), preferably in the form of a groove and a spline, which after assembly in top view resemble a circle or a circular sector. The side external parts ( 24 ) of the plates ( 1 ) at least partly constitute the casing of the device ( 2 ). The plates ( 1 ) have open passages ( 5 ) which create at least one vertical chamber ( 9 ) placed inside a rotatable ring set by key joints ( 7,8 ), and a rotating unit ( 11 ) of the plates ( 1 ) is situated inside the chamber ( 9 ). The rotating unit ( 11 ) is preferably a motor-driven, vertical rod ( 12 ) with a non fully circular section, on which a sliding body ( 14 ) equipped with a plate driver ( 15 ) for rotating selected plate (X) is mounted. The sliding body ( 14 ) of the driver ( 15 ) is joined with a movable string ( 19 ), preferably in the form of an endless belt running along the plates ( 1 ), which string prevents the plates ( 1 ) from undesirable rotation and has a recess or a break ( 21 ) aligned with the plate driver ( 15 ), the said recess or a break ( 21 ) being compatible with a blocking protrusion ( 20 ) located on each plate ( 1 ). |
