METHOD AND APPARATUS FOR ISOLATING DATA STORAGE REGIONS IN A THIN HOLOGRAPHIC STORAGE MEDIUM

摘要

A holographic storage media for storing digital data in the form of an interference grating is provided which includes a substrate (48) over which a perforated opaque structure (50) is disposed. The opaque structure (50) has wells (52) disposed therein. In the wells, a photopolymer material (54) is disposed to form data storage regions (54). This is covered by a capping layer (56). The wells (52) are chemically and/or optically isolated from each other.
