Twelve years have passed since Leith's historic paper which opened the era of modern holography. Although initially investigated for its unusual imaging properties, we have seen about five years of intensive research on the application of holography to digital data storage. Because of its unique properties, it is not surprising that attempts have been made to apply holography to such a broad range of memory and storage hierarchy. Activity has ranged from developing small-capacity, high-speed memories to large-capacity, read-only storage in the multiterabit range. Additionally, significant activity has been directed toward solving the highly specialized problems associated with ultra-high data rate recorders and reproducers. Memory systems are now, and will continue to be, the highest single cost item in the computer hardware structure. This, at least in part, accounts for the intensive research activity in optical alternatives to computer memory and storage.
