ABSTRACT:
Apparatus and method for converting a series of discrete units of incoming digital data into a set of integer values and representing said values holographically, by dimensionalizing multiple aspects of reference laser signal, and multiplexing said aspects at the same storage location. The integer set is represented logarithmically by manipulating the dimensionalized aspects in a hierarchical order, resulting in a 16-fold increase in data density at the same physical storage location, as compared with a conventional binary storage system.
