ABSTRACT:
The robust coding system makes use of a robust bar code on a label to enable a label reading system to automatically reconstruct label indicia information, even though the label has been damaged and is partially obliterated. An error correcting code is incorporated into the bar code sequence imprinted on the label to detect and correct a plurality of errors in the bar code. The error correcting bar code digits can be interleaved with the data imprinted in bar code form on the label or appended thereto. In addition, when the robust coding system is used on labels for data media cartridges, additional information is included in the bar code field to identify the type of media contained in the media cartridge.
