TL;DR: In this paper, a method for encoding data bits into channel bits used for recording digital data onto a recording medium or for transmitting digital data via a transmission system was proposed, where X designates an indefinite bit which becomes "1" when the channel bit succeeding the indefinite bit is "0" and becomes ''0'' when the corresponding indefinite bit becoming "1".

Abstract: A method for encoding data bits into channel bits used for recording digital data onto a recording medium or for transmitting digital data via a transmission system. Channel bits “00X”, “010” and “10X” are allotted to 3 patterns of data bits among 4 patterns of data bits having 2 bits, where X designates an indefinite bit which becomes “1” when the channel bit succeeding the indefinite bit is “0” and becomes “0” when the channel bit succeeding the indefinite bit is “1”. Channel bits “000010”, “00000X”, “100010” and “10000X” are allotted to 4 patterns of data bits having 4 bits which are a combination of two bits having a remaining one pattern among the 4 patterns of the data bits having 2 bits and additional two bits. Channel bits “100000010” as a special pattern are allotted to data bits having 6 bits which are the continuation of alternate 3 patterns of data bits to be encoded to channel bits “010” and data bits to be encoded to channel bits “10X”.
