Abstract:

Nowadays data storage has become an indispensable branch of computer science and technology. It plays an important role in every aspect in society, su ch as economy and national defense. Based on a review of the current development of data storage, the paper first expounds some solutions to large and high-density storages from the viewpoints of theory, technique and architecture, and proposes some ideas and research areas of the next-generation super  high-density optical storage technology. Finally the theory and relative technology of holographic storage is introduced.

Key words: （data storage;optical storage, diffraction, holographic storage）
