2000 high resolution images have been stored in a disk-type photorefractive LiNbO3∶Fe crystal using spatioangular multiplexing with a spherical reference wave. All images stored are successfully reconstructed without visuable cross talk or information loss. In this paper the angular separation between adjacent holograms in a track, as well as the radial separation between adjacent tracks are given, and the achieved performance from this memory is reported. The experimental results agree well with theory. This research demonstrated that 3-D holographic disks are feasible for mass information storage.
