Shawn - From info I compiled in http://people.bu.edu/rbs/ADSM.QuickFacts:

3590 barcode                            Is formally "Automation Identification
                                        Manufacturers Uniform Symbol Description
                                        Version 3", otherwise known as Code 39.
                                        It runs across the full width of the
                                        label. The two recognized vendors:
                                        Engineered Data Products (EDP) Tri-Optic
                                        Wright Line Tri-Code
                                        Ref: Redbook "IBM Magstar Tape Products
                                        Family: A Practical Guide", topic
                                        Cartridge Labels and Bar Codes.

I should think that those two vendors could either supply or guide you to a
supplier of such a barcode reader.
