大数据时代的光存储技术

概述了光存储技术的发展历史和现状，分析了在大数据时代光盘的作用和存在的意义。面对传统光盘容量低、速度慢等问题，介绍了能够妥善解决此问题的光盘库技术。最后介绍了可替代传统光盘的全息光存储技术。其中，同轴全息光存储既可与传统光盘相兼容，又可作为大数据高密度高速率长期保存的解决方案。

Optical data storage technologies for big data era

The history and status quo of optical data storage was reviewed in this paper. In big data era, the usage and meaningfulness of optical disc was discussed. Because of the low capacity and slow rate of optical disc, the effective technique solution of Optical Library was introduced. In the last the holographic data storage technologies as the next generation of optical disc were described. Collinear Holography is one of the technologies which can be compatible with existing disc storage systems, like CD and DVD, and enable us to store the Big Data with its high density, high data rate and long life time.
