  • The bit type holographic data storage is known to have many advantages in instrumentation for its compactness and simplicity, when compared to the 2-D page type holographic data storage. But it requires various multiplexing method for one bit hologram to achieve high storage densities. We propose an optical architecture for bit type holographic data storage which utilizes peristrophic and angular multiplexing simultaneously. Selectivity and characterization are analyzed for the proposed architecture. The possible number of multiplexing(72 bit holograms) and maximum storage densities calculation is confirmed experimentally.
