Constrained Coding Techniques for Data Storage
W. Coene, Henk D. L. Hollmann · 2003
Abstract Modulation codes such as runlength‐limited codes have been widely employed in magnetic and optical data storage systems. We review the main techniques involved in the design and use of these codes: the maximal code rate or capacity, graphical presentations of constraints, encoders and decoders, and code construction methods such as the ACH state‐splitting algorithm. We conclude this survey by discussing some recent developments and research trends.
