Either accelerated ageing tests in 1aboratories, or practical uses and results in different walksof 1ife, showed that CD-R cannot per form as a reliable medium for storing archives, althoughthe preservation life of CD-R witnessed continuous improvement; microfilm still stands to bethe best choice as a storing medium for preserving archives.
