The degradation of reconstructed images from a digital holographic memory that uses highly sensitive strontium barium niobate as a recording medium was reduced using two-dimensional modulation codes that have low average intensity and high coding efficiency. The signal-to-noise ratios of the reconstructed images and hence the bit error rates of the data retrieved from the images were improved without reducing the coding efficiency.
