Abstract

A simple 6-ary(3, 10) runlength-limited(RLL) code for a six-level optical recording channel is presented. The proposed code can be represented by a finite state diagram with six states. The code is given achieving coding density of $3.33bits/T_{min}$, which is 96.6% efficient.

광 기록 채널을 위한 간단한 6-ary(3, 10) runlength-limited(RLL) code를 연구하였다. 이 제안하는 코드는 6개의 state로 나타낼 수 있어 look-up table의 크기를 작게 할 수 있다. 또한 coding density가 $3.33bits/T_{min}$ 이며 96.6%의 code efficiency를 나타내었다.
