A system for the storage and retrieval of optical discs contains a tiltable inner housing having grooves on upper and lower walls for holding discs by their edges in a vertical orientation. A portal element, formed with a vertical slot for loading and retrieving dics, is movable across the front of the outer housing into alignment with individual disc positions of the inner housing. Flexible shutters are attached to the portal element, maintaining the entire front of the outer housing closed, except for the portal opening. The inner housing has a stable position, tilted slightly to the rear, causing the discs to roll to storage position at the back. A selected disc can be retrieved by tilting the inner housing forwardly, causing the discs to roll forwardly. All discs except the selected disc, aligned with the portal slot, are held back by the flexible shutter, while the selected disc is allowed to roll through the portal slot to an exposed retrieval position. |
