Abstract :
In this paper, we present the estimation of storage capacity in reflection-type holographic memory by using scalar diffraction theory. Signal to noise ratio in speckle shift multiplexing is derived numerically. The maximum storage capacity is presented by using signal to noise ratio and then a few tera byte is possible in a 5-inch disk.
