Abstract
A data word is error correction encoded to provide a worst case codeword without bit transitions between worst case codeword bits. A modulation bit is calculated as a function of the worst case codeword. The modulation bit has a bit polarity opposite a bit polarity of the worst case codeword bits. The worst case codeword bits are added with the modulation bit to form a modulated code word.
