Abstract: The virtual volume management system (VVM) is an improved method of managing document image files for transfer to CD-ROMs. The physical storage devices of a computer system are partitioned into logical volumes having a maximum capacity equal to the storage capacity of a single CD-ROM. One or more of these volumes are dedicated to a virtual volume set. The VVM software sets up and maintains data structures in the computer memory to maintain each of the volumes in the virtual volume set in one of three states: active, inactive, and locked. A volume in the active state is available to store document images files. Only one of the virtual volumes is active at any given time. The virtual volume management software transparently locks an active volume when it becomes full and selects another virtual volume in the inactive state as the new active volume. All data remains on-line for retrieval regardless of the state of the volume or transition of the volume to CD-ROM.
