ABSTRACT:
A machine-readable record or label includes alternating areas of different reflectivity providing a binary coded data record. The record is made by selecting the widths of the areas such that an increase in the relative widths of any two consecutive areas of different characteristics represents a binary "1" and a decrease in the relative widths of any two consecutive areas represents a binary "0". Thus, each area in the part of the code is used in the establishment of the values of two different binary bits. A method of and a system for reading or interpreting the record or label includes a pair of light reader controlled registers in which are alternately stored the widths of consecutive areas. A comparator coupled to the registers determines whether each newly stored width is greater than or less than the width of the previously stored area. In accordance with this determination, the comparator stores a "1" or a "0" in a shift register, the contents of which are transferred out as each complete character is received.
