高密度光学全息存储技术的新进展：向光盘存储挑战

光全息存储的独特优点，尤其是体全息存储的高容量和高数据传输速率，使光全息存储最有希望成为下一代海量存储技术。通过与现有的光盘和磁盘存储技术的对比，介绍了全息存储的原理和材料，以及在这一活跃的研究领域中的新进展，特别是为了提高存储容量和抑制串象噪音所发展起来的各种全息复用技术。对全息存储技术取得实用性进展的前景也作了简略讨论。

Recent Advances in Dense Holographic Storage

Holographic storage, with its high storage capacity and data transfer rate, promises to become the next generation of potential mass storage medium. A brief introduction to the principles and materials of holographic storage is given in comparison with conventional magneto optical storage. Recent advances in this area, the particales various multiplexing schemes which aim at high storage capacity and low cross talk noise, are reviewed. The paper concludes with a brief discussion of the prospects for holographic storage to become a practical technology.
