Transparent interface with direct-attached optical library data servers (i.e. optical "jukebox") provides massive, long-term storage of documents & reports. http://www-03.ibm.com/servers/eserver/iseries/optical/
And because the interface is transparent, NO USER INTERVENTION IS REQUIRED ! MIRROR IMAGE keeps track of what's where. No special requests to the I.S. staff or complicated procedures required for retrieval.
Accommodates both immediate capture to optical, and deferred ("off hours") write to optical operation.
