目前光盘已成为文献信息存储的主要载体 ,档案部门已经开始使用光盘存储档案信息 ,然而由于光盘材料成分的复杂性 ,受外界因素的影响较大 ,近年来在光盘档案的保管和利用中出现的问题越来越多。因此 ,研究影响光盘耐久性的内因和外因 ,估计光盘的预期寿命 ,如何保存光盘档案 , At present, the optical disc has become the main carrier of document information storage. The archival department has begun to use the optical disc to store the file information. However, due to the complexity of the material composition of the optical disc, it is greatly influenced by external factors. In recent years, it has appeared in the custody and utilization of optical disc files The problem is more and more. Therefore, to study the inner and outer factors that affect the durability of optical discs, to estimate the expected life of the optical discs, how to save the optical disc files,
