当前信息存储呈现出容量和速率均较低的局面,将阵列激光器、波分复用技术以及多层镀膜有机统一的三维信息存储方法应运而生。此方法主要通过光纤中耦合物镜对光斑自动拉近距离聚焦,读写海量信息,这将对三维存储寻道时间的缩减起着重要作用。本文通过对存储系统原理和光盘系统标量衍射理论的分析、浅要探究计算机仿真结果。

Since the current information storage has low capacity and rate, 3d information storage method arises, with the unity of array laser, wavelength division multiplexing technology and multi-layer coating. This method mainly uses the optical fiber cou-pling lens to pull the focus of flare closer automatically, so that to read and write huge amounts of information. It will play an impor-tant role to reduce the three-dimensional storage seeking time. This article analyzes the principle of storage system and the theory of scalar diffraction of cd-rom system, and explores on the simulation results.
