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。
The history and status quo of optical storage technology are summarized, and the function and existence of optical disc in big data era are analyzed. In the face of the problems of low capacity and slow speed of traditional optical disks, the optical disk library technology that can properly solve this problem is introduced. Finally, holographic optical storage technology that can replace traditional optical discs is introduced. Among them, the coaxial holographic optical storage is compatible with traditional optical discs, but also as a long-term preservation of high-density high-speed big data solutions.
