标准范围

ISO 18938:2008建立了数字光盘在使用过程中的护理和处理的一般原则。它解决了保存对记录数据（信息）的访问所必需的介质的物理完整性问题。ISO 18938:2008包括处理程序的建议，以最大限度地延长光盘的有效寿命。错误的处理、包装和运输技术和方法通常会对盘和记录在其上的内容造成物理损坏。延长光盘的寿命需要确定适当的处理方法，以及制定和实施良好的培训方案。为了ISO 18938:2008的目的，术语“光盘”包括压缩光盘(CD)、数字多功能光盘(DVD)、高清晰度数字多功能光盘(HD DVD)和Blu-射线盘（BD），以及这些家族的任何杂种。术语“光盘”还包括一系列中的每种类型的光盘，包括注塑[只读存储器(ROM)]、染料层[可记录(R)]和相变[可重写(RW)、随机存取存储器(RAM)]技术。虽然ISO 18938:2008中的一些建议（例如针对员工培训的建议）专门适用于大规模或长期使用，但ISO 18938:2008中所有建议的基础旨在应用于预期结果是长期使用媒体的情况，无论是档案、商业还是个人。ISO 18938:2008不涵盖磁光（MO）光盘、激光光盘（LD）或玻璃光盘。在撰写本文时，不存在HD DVD和蓝光光盘的国际标准。尽管如此，据信ISO 18938中的建议:2008年的护理和处理同样适用于他们。应当认识到，这些要求中的一些对于单个用户来说不一定可能实现。以下内容属于ISO 18938:2008的范围:使用和处理环境，包括污染物、温度和湿度以及光照；污染问题；检查；清洁和维护，包括清洁方法和频率；运输；灾害，包括水、火、建筑和灾后程序；员工培训。

ISO 18938:2008 establishes general principles for the care and handling of digital optical discs during use. It addresses the issues of physical integrity of the medium necessary to preserve access to the recorded data (information). ISO 18938:2008 includes recommendations for handling procedures to maximize the effective life of optical discs. Faulty handling, packing and transporting techniques and methods often cause physical damage to the discs and to the content recorded thereon. Extending the longevity of optical discs requires the identification of appropriate handling methods, as well as well-developed and implemented training programs.For the purposes of ISO 18938:2008, the term “optical disc” includes the families of compact disc (CD), digital versatile disc (DVD), high definition digital versatile disc (HD DVD) and Blu-ray disc (BD), and any hybrids of these families. The term “optical disc” also includes each type of disc within a family, including injection moulded [read-only memory (ROM)], dye-layer [recordable (R)] and phase change [rewriteable (RW), random access memory (RAM)] technologies.While some of the recommendations in ISO 18938:2008 (e.g. those for staff training) apply specifically to large-scale or long term usage, the basics of all recommendations in ISO 18938:2008 are intended to be applied in circumstances where the desired result is long-term usage of the medium whether archival, commercial or personal.ISO 18938:2008 does not cover magneto-optical (MO) discs, laser discs (LD) or glass discs. At the time of writing, International Standards do not exist for HD DVD and Blu-ray discs. Nonetheless, it is believed that the recommendations in ISO 18938:2008 for care and handling can equally apply to them. It is recognized that some of these requirements are not necessarily possible for the individual user to achieve.The following are within the scope of ISO 18938:2008:

• use and handling environments, including pollutants, temperature and humidity and light exposure;
• contamination concerns;
• inspection;
• cleaning and maintenance, including cleaning methods and frequency;
• transportation;
• disasters, including water, fire, construction and post-disaster procedures;
• staff training.
