光盘是继纸张、胶片和磁带介质后又一种存储介质。光盘因具有容量大、存储密度高、单位成本低、工作稳定可靠、抗干扰能力强、保存寿命长、便于携带和使用、信息还原效果好和应用范围广等特点,迅速成为载体材料的宠儿,并得到广泛地应用。在光盘被大量使用的同时,问题也在不断地出现。有关部门通过问卷调查和实地调研,了解到目前文献信息部门对光盘的保护处于比较落后的状况,有的单位早期保护的光盘已经出现问题,如光盘上出现氧化的斑点,有的光盘上的信 Discs are another storage medium after paper, film, and tape media. Due to its advantages of large capacity, high storage density, low unit cost, stable and reliable operation, strong anti-interference ability, long shelf life, easy to carry and use, good information recovery effect and wide application range, the optical disc has quickly become the darling of carrier materials, And has been widely used. As CDs are used in large numbers, problems are constantly emerging. The relevant departments through the questionnaire survey and field research found that the current literature and information departments on the protection of optical discs in a more backward situation, some units of the early protection of optical discs have problems, such as the disc appears oxidized spots, and some disc letter
