摘要
不断提高存储介质的存储容量和存储密度是信息科学的研究热点之一,在三维空间中进行数据存储将大幅度提高存储密度和存储容量,是实现超高密度光存储的有效方法。介绍了双光子吸收光存储、光谱烧孔光存储、激光全息存储和透明介质的飞秒脉冲体存储等三维光存储的进展、数据存储的原理以及各种存储方法有待解决的问题。
Continuously increasing storage density and storage ability is one of the hot issues of information science. Three-dimensional optical storage is an effective way to solve this problem in highest measure for realizing extreme large recording capacity. And then the progress of three-dimensional optical storage, the principle of data storage, as well as problems of various ways of storage need to be solved about 2-photon 3D optical storage, spectral hole burning for data storage, holographic storage, and three-dimensional optical storage in transparent material using a femtosecond pulsed laser.
