Abstract: An archival and retrieval system which is connected to a host computer through an asynchronous serial line. The system operates unassisted through this serial line and appears like another terminal to the host. The system includes an archival and retrieval workstation containing archival and retrieval software for controlling the memory management operations. A portion of the archival and retrieval software resides in the host and contains archival and retrieval stacks for receiving and storing archive and retrieve requests respectively from user operated terminals. At periodic intervals the archival and retrieval workstation polls the archival and retrieval stacks to see if there are any requests present. If there are, the request is transferred to the workstation and used to either store or fetch the appropriate data item. The archival and retrieval workstation includes an archival storage media such as a optical disk.
