Abstract
Disclosed are a method and device of converting data words into code words. This method inserts 2p guided bits before inputting each set of data words, performs a pre-defined operation, and generates 2data sequences with different guided bits. It chooses q data sequences from the 2data sequences for coding, performs a run length limited (RLL) coding with a coding rate m/n, and generates q (d, k) constrained code word sequences. Finally, an optimal (d, k) constrained code word sequence is selected from the q (d, k) constrained code word sequences. The device reduces the circuitry of the RLL coding applied guided scrambling without losing the control of direct current and low frequency components.
