Digital-Imaging and Optical Digital Data Disk Storage Systems: Long-Term AccessStrategies for Federal Agencies

摘要

Federal agency officials responsible for records with long-term value should findthis report's recommendations useful in designing and implementing a digital imaging and optical disk storage system. This report discusses critical management issues relative to technological developments, data migration, and long-term access to information. The report consists of an executive summary and an overview of the challenges involved in long term data access, followed by five sections that describe digital image capture, indexing systems, optical digital data disk storage systems, information retrieval, and information management policy considerations. Each of these five main report sections features management issues, technology trends, user experiences, and recommendations. Four appendices to the report include: detailed site visit descriptions of fifteen federal agencies currently using optical media for storing mission critical information; the status of optical disk related standards projects; a glossary of terms and acronyms; and a bibliography of sources.
