Use of Laser Barcode Scanner to Detect Cartridges Upside Down in
Library

      A method for detecting tape cartridges inadvertently placed
upside-down in a storage cell within an automated tape library is
disclosed.

      Utilizing a barcode reader already present in the library for
the purpose of scanning tape cartridge labels, the barcode reader has
been enhanced to report not only the cartridge label but also the
orientation of the label, that is, whether it was read with a forward
scan or a reverse scan.  Knowledge of the label orientation allows
the automated tape library system to know if the cartridge label is
upside-down or right-side-up.  The automated tape libraries can then
take appropriate action if the label is upside-down.
