Paper Abstract

The memory system described herein can record multiple holograms by a simple shift of the photopolymer film medium. The primary advantage of this method is that it enables the generation of make a single, large capacity hologram because the corresponding optical system is simpler than the transmission-type recording system, which has generally been studied to date. The experimental results confirm the possibility of multiple recording by medium shift. Furthermore, the results indicate that a large capacity memory system of over 1 Tb/in2 can be obtained if a thick medium (about 1 mm) is used.
