The recent research progress of volume holographic data storage is briefly described. The key technologies of miniaturization and practicality of volume holographic storage system are discussed. The structure, multiplexing and addressing of holographic storage system are optimized. Based on this, It has a storage density of 10 Gb / cm3 and has the function of multi-page high-speed parallel correlation recognition and recognition with a recognition rate greater than 2000 frames per second. The new concept of dynamic speckle multiplexing The dynamic speckle-angle hybrid multiplexing technology has an 8-fold improvement in multiplexing sensitivity over the simple angle multiplexing, providing an effective way to further improve the storage density. It shows that the volume holographic storage system has the advantages in mass storage and optical parallel processing Great potential for application.
