Method for storing multiple files without header information and for each storage medium maintaining a separate stored index including header information for each file

摘要

A headerless data storage format is implemented in a library environment. The header information, otherwise stored on the data storage media, is consolidated in one or more indices of the library, thus freeing the media from header information. To export an existing storage medium from the library, the storage medium is modified to include the previously missing header information and then ejected from the library; the medium is thus compatible, as a self-sufficient unit, with other libraries or standalone data storage drives. Conversely, to import a new storage medium containing data and interspersed header information, the medium is received into the library, whereupon the header information is removed from the medium and stored in the appropriate index.
