High Density Digital Data Recording System.

Abstract : The state-of-the-art in High Density Digital Data Recording is such that it is now possible to evaluate the capabilities of write-once-read-many (WORM) laser disc systems vis-a-vis magnetic tape spooling. Most of such a systems' components can be purchased off the shelf. The potential to store unalterable data , in vast amounts, in a small space, or a medium impervious to time degradation can be realized with current technology.
