Recording tape cartridge and barcode label reissuing method

A method for reissuing a barcode label for a recording tape cartridge comprising a case that accommodates a reel around which a recording tape is wound and a label attached to a label surface formed at a wall surface of the case, the wall surface being located at a side opposite to a direction in which the case is loaded into a drive device, wherein the label includes a first label layer, attached to the label surface, on which individual identification information is displayed in a two-dimensional code and a second label layer attached to the first label layer with a peelable bonding force, the second label layer being capable of covering and concealing the two-dimensional code, the individual identification information being displayed in a barcode on the second label layer, and the two-dimensional code being displayed at a central part in a longitudinal direction of the label, the method comprising:

• peeling off the second label layer from the label attached to the label surface of the recording tape cartridge;
• reading the two-dimensional code displayed on the first label layer from which the second label layer has been peeled off;
• and
• creating a new second label layer on which the individual identification information is displayed in a barcode, based on the two-dimensional code read on the first label layer.
