Development of Nano-gel Photopolymer Recording Material for Phase-lock Collinear Holographic Memory System

Abstract

SynopsisThe phase-lock collinear holographic data storage is the promising candidates of optical data storage for the nextgeneration. The extreme noise reduction is one of most important requirements to realize the phase-lock recording media with the make of multi levels of phase-based gray-level data page for recording. We tried to design the photopolymer as a recording material based on the nano-gel photopolymer having the nano scale reaction site for the photoreaction of high refl ective index acrylates. In this paper, we show the results of our development of the recording material based on nano-gel photopolymer.
