This International Standard establishes general principles for the care and handling of digital opticaldiscs during use. It addresses the issues of physical integrity of the medium necessary to preserve accessto the recorded data (information). This International Standard includes recommendations for handlingprocedures to maximize the effective life of optical discs. Faulty handling, packing and transportingtechniques 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, aswell as well-developed and implemented training programs.For the purposes of this International Standard, the term “optical disc” includes the families of compactdisc (CD), digital versatile disc (DVD), high definition digital versatile disc (HD DVD) and Blu-ray disc(BD)1), and any hybrids of these families. The term “optical disc” also includes each type of disc withina family, including injection moulded [read-only memory (ROM)], dye-layer [recordable (R)] and phasechange [rewritable (RW, RE), random access memory (RAM), and recordable (BD-R)] technologies.While some of the recommendations in this International Standard (e.g. those for staff training) applyspecifically to large-scale or long term usage, the basics of all recommendations in this InternationalStandard are intended to be applied in circumstances where the desired result is long-term usage of themedium whether archival, commercial or personal.This International Standard 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 this International Standard for care and handling can equallyapply to them. It is recognized that some of these requirements are not necessarily possible for theindividual user to achieve.The following are within the scope of this International Standard:— 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.The quality of the data written on the disc is outside the scope of this International Standard. However,a high quality result of the recording phase is important to the longevity of information. It is advisablethat a rigorous program of data integrity testing be implemented, as this forms an obligatory part ofall digital long-term storage. In addition, when keeping digital information for archival purposes, it isadvisable that a multiple copy/multiple location strategy be in place.
