Subject: Magnetic media
The Commission on Preservation and Access in collaboration with the National Media Laboratory have undertaken an applied research project entitled "Archival Management of Materials Created on Magnetic Media." The NML brings to the collaboration, an extensive program of experimental research and mathematical modeling on a range of magnetic media types. These data track media stability on such physical and chemical properties as: binder hydrolysis, remanence, coercivity, top coast adhesion and friction. Changes in these properties are plotted over time at various temperatures and relative humidities. The Commission and the NML will be seeking to develop management tools for Preservation Administrators based upon NML's research. However, in order to concentrate on the types of media that make most sense to libraries and archives, assistance is sought in the following areas: * Types of magnetic media that make up the bulk of extant collections. * Types of media used or contemplated for migration or back-up. * And/or types by manufacturer, magnetic particle, binder and substrate. Preservation Administrators who feel that they might be able to contribute but require more information are requested to contact: James R.
