Holographic storage of multiple high-capacity digital data pages in thick photopolymer systems

Multiple digital data pages (480 kbits per page) were holographically recorded and retrieved with low bit-error rates in thick ($\sim 250‐$ and $\sim 500‐\mathit{\mu }\mathrm{m}$) photopolymer media. The photopolymer systems were fabricated with the optical quality and low level of scatter required for digital data storage. We believe that these results represent the first demonstration of holographic storage of high-capacity digital data pages in photopolymer media with the thickness that will be required for such storage densities.
