Paper Abstract

Multilevel recording has been demonstrated to significantly increase the linear densities achieved with standard methods of binary encoding in optical data storage systems. In this paper we introduce the theoretical concepts and practical coding aspects behind multilevel optical recording system. We show that there are three-stage coding flow and explain how to design and implement the encoder. As an example we give a 5th-power finite state transition diagram of q=8 RLL (2, 10) encoder and compute its adjacent matrix. Especially we discuss the implement method to quickly search decoding table of slider decoder by way of computing the least Hamming distance.
