The erase media feature erases data from a unit of media but leaves the media header information intact. Header information comprises the information entered when the media was prepared: media name, owner, rights, and other information. It is better to erase media rather than reformat media whenever possible. When media is erased, an "erased" flag is added that can easily be overwritten.

If it is part of a multi-level storage hierarchy where files are migrated and replicated, viable data on the media must be moved to other media and the original media erased in order to purge old, expired data.|
|•||When media is used in a cycled Information Repository. At the end of a cycle, the old media being reintroduced needs to be erased by the Information Repository before it can be reused.|
