Abstract
Abstract A machine-readable record or label includes alternating areas or bars of different reflectivity whose relative widths are varied to provide a binary coded data record. The record includes start and stop codes between which is recorded a plural character message capable of being read in forward and backward directions. A record interpreting system compares the widths of consecutive bars and, by reference to the sequence in which the bars are read, enters binary ''''0''''s and ''''1''''s into a shift register. The system includes a detector that continuously samples the shift register contents for a start indication and, on detection thereof, stores a start and the direction of reading. This changes the system from a scan mode to a read mode in which the contents of the shift register are transferred to a display only as each complete character code is received. The system includes a reversing and complementing control for reverse read codes and both error and message end detecting means for returning the system from a read mode to a scan mode.
