Holographic storage device with faceted surface structures and associated angle multiplexing method

摘要

A holographic storage apparatus is provided which comprise: a photorecording medium layer which includes a first side and a second side and which encompasses a plurality of volume holographic storage regions; a plurality of first surface structures disposed on the first side of the photorecording medium layer, respective first surface structures including respective first and second facets that upstand from the first side of the photorecording medium; and a corresponding plurality of second surface structures disposed on the second side of the photorecording medium layer, respective second surface structures including respective third facets that respectively upstand from the second side of the photorecording medium layer parallel to respective first facets of corresponding respective first surface structures; wherein each respective volume holographic storage region is disposed between a respective first surface structure and a respective corresponding second surface structure.
