A lecture on the history, use, and backscatter applicability of balance codes. Balance codes (also called recording codes, channel codes, line codes, or modulation codes) have been used in magnetic tape drives, swipe cards, optical disks, and many more places. This lecture discusses and updates the concept with respect to backscatter channels.
