We have developed a document storage system using a one-terabyte Mass Storage System that has 1,600 rewritable optical disks. This system can store up to 20 million document pages. A file management subsystem frees the used from file and disk management. The document entry time is five seconds per page. The remote retrieval time for one page is 1.5 seconds for a 10 - Mbps Local-Area Network and two seconds for a 1.5 - Mbps Integrated Services Digital Network. Documents can also be entered from distant G3 and G4 facsimile machines and can be sent to them.
