In the era of information explosion, the demand of data storage is increased dramatically. Holographic data storage technology is one of the most promising next-generation data storage technologies due to its high storage density, fast data transfer rate, long data life time and less energy consumption. Collinear holographic data storage technology is the typical solution of the holographic data storage technology which owns a more compact, compatible and practical system. This paper gives a brief review of holographic data storage, introduces collinear holographic data storage technology and discusses phase modulation technology being used in the holographic data storage system to achieve higher storage density and higher data transfer rate.

利用一种生物光致变色材料—基因突变菌紫质BR-D96N薄膜的光致变色特性，实现了可擦写式共线全息图像存储实验.对于光密度为3.0的BR-D96N薄膜，在700 mW/cm2的记录光强下(波长为632.8 nm，物光、参考光光强比为约1∶1.2)，全息图建立的最佳曝光时间约为3s，最佳再现光强约为50 mW/cm2，全息图寿命约为10 min.实验表明：共线全息存储技术光学系统简单，系统体积小，受存储环境的影响低，并能够实现高密度存储；同时也实验验证了BR-D96N薄膜具有响应速度快，感光灵敏度高，擦写次数高，稳定耐用，使用方便等优点，可以作为一种较灵敏的可擦写共线全息记录介质.
