Paper Abstract

We discuss the use of pulse length modulated recording of run-length-limited sequences of p-ary digits pi ε {0, 1,... p-1}; p≥3, to effect the physical representation of digital data on a storage medium that supports three or more distinct recording levels, or types of marks. p-ary run-length-limited modulation codes that facilitate the implementation of the modulation technique are also described. We also introduce a novel error correction coding technique that enables detecting/correcting errors in the values of the non-'zero' digits in the p-ary run-length limited sequence recovered from the storage medium.
