Prediction of the Long Term Stability of Polyester-Based Recording Media. First Annual Report, June 1982; Second Annual Report, August 1983; Progress Report, December 1984.
Brown, Daniel W.; And Others
This document comprises three progress reports for a 5-year environmental aging study aimed at establishing the lifetimes of magnetic tapes and the poly(ethylene terephthalate) (PET) base of photographic and electronic film under archival storage conditions. The first annual report (1982) introduces the rationale for the project, provides background information on PET and a review of selected aging studies involving PET, and describes the scope of the current project. The second annual report (1983) provides the results with PET in the first year as well as descriptions of the second year experiments and their subsequent findings. The progress report (1984) summarizes the two annual reports, discusses their findings, proposes further research, and states conclusions for PET films. Each section of the document contains its own set of references, as well as data tables and graphs which support the study's findings. (JB)
