Recording tape cartridge, barcode printing system, barcode printing method, and method of manufacturing recording tape cartridge with barcode

A barcode printing system comprising:

• a conveying unit that conveys a recording tape cartridge including a case that has a first half, in which a first peripheral wall is erected around a top plate, and a second half, in which a second peripheral wall is erected around a bottom plate, the first half and the second half being joined to each other in a state in which the first peripheral wall and the second peripheral wall abut against each other, the case storing a reel on which recording tape is wound, and including a label surface formed by a first half label surface of the first peripheral wall and a second half label surface of the second peripheral wall on a side opposite to a loading direction of the case with respect to a drive device;
• and
• a printing unit that prints a one-dimensional or two-dimensional barcode in which individual identification information is recorded only on the first half label surface or the second half label surface of the recording tape cartridge conveyed by the conveying unit.

A barcode printing method comprising:

• a base printing step of printing a white base on at least one of a first half label surface or a second half label surface, of a recording tape cartridge that includes a case that has a first half, in which a first peripheral wall is erected around a top plate, and a second half, in which a second peripheral wall is erected around a bottom plate, the first half and the second half being joined to each other in a state where the first peripheral wall and the second peripheral wall abut against each other, the case storing a reel on which recording tape is wound, and that includes a label surface formed by the first half label surface of the first peripheral wall and the second half label surface of the second peripheral wall on a side opposite to a loading direction of the case with respect to a drive device, the recording tape cartridge being conveyed by a conveying unit;
• and
• a barcode printing step of printing a one-dimensional or two-dimensional barcode in which individual identification information is recorded only on the base printed on the first half label surface or the base printed on the second half label surface.
