This report examines the evaluation of accurate replication of data during digital tape to digital file migration, essential to ensuring the authenticity and integrity of the resulting digital file. To illustrate the challenges and strategies in the migration of digital data from a physical object to a file-based system, the report begins by examining the storage of data in UPC barcodes. It then focuses specifically on the preservation of digital DV videotapes: illustrating types of video concealment and audio errors; briefly explaining how theDVAnalyzer toolallows the archivist to identify the location of errors, allowing the focus of quality control to sections of DV files that are identified as having errors; and finally demonstrating how various software and hardware migration configurations produce differing results. It concludes that not only the quantitative results of a file after migration matter, but the physical components of tape and playback machinery play an important role.
This report is an important contribution to ensuring integrity and authenticity in DV videotape migration and is especially informative for those archivists working with this type of format. It is considered by the field to be essential reading on the subject.
