Abstract: PURPOSE: To constitute a method and apparatus for writing a bar code in a continuous pattern by adding a step for marking a substrate so as to obtain a serpentine pattern having a connection segment for alternately linking data segments at both ends. CONSTITUTION: A series of connection segments for linking adjacent bar code data segments are used. These connection segments are set to the ends of the data segments to suitably connect the data segments vertically. However, the connection segments may be actually patterns such as circular arc patterns or the like corresponding to the continuous operation of a laser. In order to provide continuity to a writing path, the connection segments are alternately arranged so as to obtain a serpentine pattern. Further, in order to accurately start the laser operation to a substrate, especially, in such a case that the substrate is plastic or metal, the start segment vertically extending outwardly from one end of a first data segment is used. Therefore, the effect of laser irradiation on the substrate is continued to become uniform.
