Large document volumes can fill up even today's multi-gigabyte hard disks quite rapidly. Therefore, document images are best stored on a medium which is both permanent and inexpensive. An optical disk costing less than $100 can store over 28,000 scanned document pages!

These optical disks are usually stored in an optical jukebox. Optical disks are accessed in an optical jukebox the same way that a music jukebox accesses a particular CD to find the track you select. The document is then retrieved from the optical disk and displayed on the retrieval PC workstation.
