Paper Abstract

For optical memory based on reversive photothermoplastic information carriers, a hologram recording mechanism for short expositure time (to picoseconds) and high-photosensitivity photothermoplastic materials for holographic information recording are considered. It is shown that the latest achievements in the branch of high-sensitive (10-6 J/cm2) materials and multielements high-speed (response time of 200 kHz) liquid crystal 1D modulators with 1000 elements allow us to achieve for real optical memory systems based on moved film carriers the data rate of 28 Mbytes/s and storage capacity of 3 Gbytes. The limit opportunities of such memory are considered. The described memory can be used with high-speed correlative or neural-network information processing.
