全息存储

激光全息存储技术是一种利用激光全息摄影原理将图文等信息记录在感光介质上的大容量信息存储技术，它有可能取代磁存储和光学存储技术，成为下一代的高容量数据存储技术。传统的存储方式将每一个比特都记为记录介质表面磁或光的变化，而全息存储中将信息记录在介质的体积内，而且利用不同角度的光线可以在同样的区域内记录多个信息图像。
另外，磁存储和光存储每次都只能读写一个比特的信息，而全息存储可以并行的读写数百万比特，这样可以使信号的传输速率大大超过目前光存储的速度 。

Holographic data storage 全息存储
Holographic data storage is a potential technology in the area of high-capacity data storage currently dominated by magnetic data storage and conventional optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium. Holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same area utilizing light at different angles.
