Abstract
A method and apparatus is provided for producing single width barcodes in a continuous, serpentine pattern. This pattern provides continuity of operation for laser marking instruments and thereby results in the formation of more uniform and higher quality barcode indicia. The use of a continuous serpentine pattern also increases the speed at which the code may be written onto a substrate. This marking method is particularly appropriate for use in marking a wide variety of materials including semiconductors, metals, plastics and ceramics.
