【摘要】 光致变色多波长多阶存储是基于光致变色原理的一种高容量光存储方法,利用多波长并行读写和多阶存储的方法可以明显地提高存储容量和存储速度。对多波长多阶光存储的存储原理、存储系统和光盘结构、写入读出过程以及今后的研究方向进行了论述。更多还原

【Abstract】 The photochromic multi-wavelength multi-layer was a kind of high density optical storage method based on the principle of photochromic. The storage capacity and velocity could be absolutely improved by the technology of multi-wavelength parallel read-write and multi-layer storage. Researches were summarized about the principle of multi-wavelength multi-layer, storage system, construction of disk, process of read-write and future development.更多还原
