Method for generating a RLL code

摘要

A code word includes a first group of data bits and code bits that represent a second group of data bits. The code word may have a minimum probability of bit transitions among its bits. It may include a parity bit. A code that includes such a code word can have both a high efficiency and small error propagation. By including fewer bit transitions, a sequence of such code words causes less read noise, and fewer read errors. A parity bit allows improved error detection. Such a code word can significantly increase the effective write and read speeds of a disk drive. <IMAGE>
