Photopolymer media design for collinear holographic data storage

The recording property of newly developed photo-polymer for Holographic data storage (HDS) was studied. We designed two types of photo-polymers; Type-A and Type-B. Type-A is developed to be suitable for the collinear system. Type-B is designed by using conventional technology. The dependence of recording property on write energy was investigated. It was found that Type-A had higher sensitivity (0.16mJ/cm 2 ), which indicated the capability of recording by a few pulse exposure, and lower scattering property. We also investigated recording property of shift multi-plexing.
