Abstract
Holographic storage mediums, methods for producing the storage medium, methods for storing data in the holographic storage medium, and optical storage reading methods are described herein. The holographic storage medium can be formed from a composition comprising a thermally crosslinked polysiloxane binder; a photoactive material; and a photo-initiator, wherein the photoactive material has a concentration that remains about the same before and after a thermal cure process to form the thermally crosslinked polysiloxane binder.
