Study on the life test of optical information storage materials

With large storage capacity, low cost and long storage life, optical holographic storage technology has great application potential to meet the demands of quick data exchange and cold data storage. Accurate and standardized testing procedure of disc storage life about new optical storage media materials has become an important challenge. In view of the new optical storage technology, we discuss and analyze the applicability and limitations of the application of holographic optical disk life test through the existing domestic and foreign disc test standards. Because of materials changing in the holographic disc, we propose and optimize an aging test model and test procedure based on several discs aging test models. And also hope to provide a reference for the establishment of life test standards for holographic optical storage discs.
