MEDIA, SYSTEMS AND METHODS FOR OPTICAL DATA STORAGE

Embodiments of the invention disclose a media, systems and methods for optical data storage. A nanocomposite material for use as an optical data recording medium comprises nanoparticles embedded in ahost matrix, wherein the host matrix comprises a material having a high structural stability, and the nanoparticles comprise optical functional components having a first physical or chemical state anda property of permanent transition to a second physical or chemical state upon exposure to corresponding optical radiation, whereby information may be recorded in the first and second physical or chemical states of the optical functional components over an extended time period. 本发明实施例公开了种提供了用于光学数据存储的介质、系统和方法。用作光学数据记录介质的纳米复合材料包括被嵌入在主体基质中的纳米粒子，其中，主体基质包括具有高结构稳定性的材料，并且纳米粒子包括光学功能成分，该光学功能成分具有第物理或化学状态并且具有在暴露于相应的光辐射时永久转变至第二物理或化学状态的性质，从而可以在延长的时间段内以光学功能成分的第物理或化学状态和第二物理或化学状态来记录信息。
