ABSTRACT:
A run length limited (RLL) code generation method for a data storage device is provided. In the RLL code generation method for generating a predetermined number of bit codewords, sequences of 16-bit data are received, and then sequences of 17-bit codewords are produced, wherein the sequences of 17-bit codewords has a first predetermined number of successive zeros as a maximum run length of zeros, and the sequences of 17-bit codewords include two subsequences each having a second predetermined number of successive zeros as a maximum run length of zeros. Thus, the RLL code generation method is helpful for an equalizer and provides a high recording density as well as a higher signal transmission rate compared to a rate 8/9(0,4/4) coding method.
