ABSTRACT:
A method of encoding digital information in a system is provided. The method includes receiving a sequence of user-bits and calculating a running digital sum (RDS) of the system. Also, a code word is generated based on the sequence of user bits and the RDS of the system to maintain the RDS of the system calculated with the code word to within a selected range. In one embodiment, the sequence of user bits is 19 bits and the code word is 20 bits.
