Abstract
In this paper, we propose the enhancement technique of the storage density in the disk-type memory with photorefractive cross polarized four-wave mixing. We calculate the amounts of shift that enable us to distinguish adjacent signals in the directions of the circle and the radius of the disk, and we carry out experiments to verify the analytical results. Also we investigate the temporal property of cross polarized four-wave mixing to estimate the optimum exposure time.
