Title: Modulation system

Abstract: A 6-bit output code word is generated in response to every 4-bit input code word by referring to a set of encoding tables. The encoding tables contain output code words assigned to input code words, and contain encoding-table designation information accompanying each output code word. The encoding-table designation information designates an encoding table among the encoding tables which is used next to generate an output code word immediately following the output code word accompanied with the encoding-table designation information. The generated output code words are sequentially connected into a sequence of the generated output code words which follows predetermined run length limiting rules (1, k)RLL, where "k" denotes a predetermined natural number between 7 and 12.
