Abstract
A bar code is formed of a number of parallel bars adapted to be provided circumferentially on a tubular or rod-like work and extend spirally about the center line of the work. In an alternative form, the bar code includes a number of parallel bars each adapted to extend continuously along the entire length of the work. In another alternative form, the bar code includes a number of parallel bars adapted to be provided on the surface of a belt-like work and each adapted to extend continuously along the entire length of the work.
