In this paper, we presented a computer simulation analysis of high-density hologram recording, which is a promising mass optical memory technique. A simulation method for off-axis speckle-shift multiplexed recording by three-dimensional computer simulation analysis was presented, as well the signal evaluation of recording and reproduction. By this simulation method, the characteristic features of recording and reproduction are studied from the viewpoints of signal-to-noise-ratio and the reproduced image's quality, and a high-density speckle-shift multiplexed recording condition is proposed.
