Abstract

The capacity of holographic memory can be made higher than that of the conventional optical disks because it can use 3D memory storing area. This paper discusses ROM type holographic memory that uses CGH for data storing. High speed calculation method for creation of CGH is studied. By the experiment and simulation to create the Lohmann type CGH pattern by the optical disc cutting system, it was shown that the creation of CGH pattern that can generate high quality reconstructed 2D image is feasible by this method.
