多维度信息记录与再现技术的进展

Process of Multi-dimensional Information Recording and Reproduction Technologies

随着信息技术的高速发展和大数据时代的到来,有效存储和管理海量数据的要求对数据存储技术提出了严峻挑战。光存储技术在能耗、容量、成本、寿命、安全等方面的优势,使其正逐渐成为未来数据存储的主流技术。本文围绕光存储技术的维度展开论述,纵向介绍了几种常用的光存储技术。目前以光盘为代表的二维面存储技术,存储容量已接近其理论存储极限(23.5 GB/disc);以双光子吸收技术、全息存储技术为代表的三维体存储技术,其存储容量相较二维存储技术提升了2~4个数量级;五维存储技术进一步扩展了数据存储的维度。可以预见,未来光存储技术会在大存储容量、超高存取速度、高性能存储材料、多维度存储技术等方面取得突破和进展。

With the rapid development of information technology and the arrival of information explosion era,the effective storage and management of massive data puts forward a serious challenge to data storage technology.Optical storage gradually become a mainstream technology for data storage due to its advantages in terms of energy consumption,capacity,cost,longevity,and security.The dimensions of optical storage technologies are focused to introduce several common optical storage technologies in this paper.At present,the storage capacities of two-dimensional surface storage technologies have approached theoretical storage limit(23.5 GB/disc).Three-dimensional storage technologies contain two-photon absorption technology,volume holographic storage technology and so on.Those capacities are improved by 2 to 4 orders of magnitude compared with two-dimensional storage technologies.Five-dimensional storage technology further expands the dimensions of data storage.Predictively,optical storage technologies will achieve big breakthroughs and progresses in the field of large storage capacities,ultra-high access speed,high-performance storage materials,and multi-dimensional storage technologies.
