Abstract
An optical bar code reader includes a pair of clock sensors and a pair of data sensors for respectively reading the data track and clock track of the optical bar code. The data track sensors are offset from the clock track sensors and the data and clock track sensors detect changes at the edges of the bars in the optical code.
