Abstract
An encoded label for a magnetic tape cartridge includes a substrate having an obverse side and a reverse side. The reverse side is adapted to be affixed to the magnetic tape cartridge, while the obverse side has pre-printed thereon at least two redundant indicators for identifying the magnetic tape cartridge to which the label is affixed. Each of the indicators include a plurality of characters, but the characters of one such indicator are scrambled with respect to the characters of the other indicator, thereby permitting accurate identification of the magnetic tape cartridge by an optical scanner in spite of the label's having a substantial portion missing or obliterated.
