Abstract

Our goal is increase the storage density of our rewritable holographic memory card system based on thin film polymer media on credit card size plastic carriers. We use computer simulation to optimize the illumination and the Fourier filtering in order to have optimal trade-off between bit error rate and data density.We also investigate the possibility of using gray scale data coding.

Key words
