Abstract

U. S. Patent 4,115,768 discloses a system for encoding serial data to be stored on a disk file in a 2-7 run-length limited code and for decoding the 2-7 stored data back into a serial bit stream. As disclosed in that process, both the encoder and decoder employ a shift register and a system of combinatorial logic.
