Abstract
Source data each consisting of m-bits can be converted into conversion codes each consisting of n (>m) bits with ease, and reverse conversion thereof can be performed with ease. The code conversion and the reverse conversion can be characterized in terms of a series of tables. The current input source data and the next input source data are respectively taken in by registers. Whether or not the run length at a connecting portion between consecutive source data satisfies conditions is determined by a control unit, and a table to be used is selected to finally obtain a conversion code.
