Recording Media That Exhibit High Dynamic Range for Digital Holographic Data Storage
01 April 1999
A general strategy for fabricating thick, optically flat photopolymer recording media with high dynamic range (M/#) that exhibit low levels of recording-induced Bragg detuning for holographic data storage is presented. In particular, media with M/#s as high as 42 in 1 nm thick formats are obtained. We believe these results are the first demonstration of a holographic storage medium with dynamic range of this magnitude. In addition, we report the holographic recording and recovery of high capacity (480 kbit) digital data pages in these media, further illustrating their data storage capabilities.
