A three dimensional optical data storage and retrieval system that includes a three dimensional optical data storage medium and an apparatus for providing access to data stored on the medium. The data storage medium includes an optical data storage material which either a low molecular weight or polymeric glassy solid that are capable of undergoing multi-photon excitation that are energetically different in the write and read cycles. The optical data storage materials provide substantially higher storage capacities relative to conventional materials, and show high robustness in that written and stored data can undergo multiple read cycles without erasure or overwriting. An apparatus for data recording and accessing stored data on the medium includes a controllable variable energy photo-emitting excitation source and an emission photo-detector.
一种三维光学数据存储和检索系统,包括一个三维光学数据存储介质和一个提供访问介质上存储数据的设备。数据存储介质包括一种光学数据存储材料,其为能够在写入和读取周期中产生不同能量的多光子激发的低分子量或聚合物
玻璃固体。光学数据存储材料相对于传统材料具有明显更高的存储容量,并且在写入和存储数据可以经受多次读取周期而不会被擦除或覆盖的情况下表现出高度的稳健性。用于在介质上记录数据和访问存储数据的设备包括可控的可变能量光发射激发源和发射光电探测器。
