Abstract :
In magnetic or optical storage devices, it is often required to map the data into runlength-limited sequences. To ensure that cascading such sequences does not violate the runlength constraints, a number of merging bits are inserted between two successive sequences. A theory is developed in which the minimum number of merging bits is determined, and the efficiency of a runlength-limited fixed-length coding scheme is considered
