可记录光盘稳定性比较——严酷条件下的错误率研究

Stability Comparison of Recordable Optical Discs-A Study of Error Rates in Harsh Conditions

任何存储媒体的可靠性和寿命对于档案保管员、保护主义者以及重要信息的创作者都是十分关注的问题。特别是在诸如DVD和CD光盘等数字媒体的情况中更是如此,因为足够数量的错误会致使光盘变得无法读取。

The reliability and longevity of any storage medium is a key issue for archivists and preservationists as well as for the creators of important information. This is particularly true in the case of digital media such as DVD and CD where a sufficient number of errors may render the disc unreadable. This paper describes an initial stability study of commercially available recordable DVD and CD media using accelerated aging tests under conditions of increased temperature and humidity. The effect of prolonged exposure to direct light is also investigated and shown to have an effect on the error rates of the media.
