Holographic memories are expected to be used as high capacity portable media. The memory capacity of holographic memories can be made higher than that of the conventional optical disks vecause the holographic memories can use 3D memory storing. Also, the data transfer rate of holographic memories can be easily increased by the use of batch recording/reconstruction of 2D digital data. Recently, photopolymer has been studied as a candidate memory medium. However, this medium shows shrinkage after recording, which makes it difficult to do multiple recording. This paper clarifies the degree of this medium shrinkage that occurs after recording and its effect on bit error rate. Also, the paper explains how the bit error is greatly reduced when the image distortion caused by the shrinkage is corrected.
