Abstract
In this paper we consider theoretical and practical aspects of a multilevel, re-writable and write-once optical recording system with compact disc parameters. A linear time invariant channel model is presented. We compare fixed-length and variable length runlength limited (RLL) coding and find that for the mark lengths of interest (600 nm for CD) M=4 is the optimum number of levels for RLL coding. For fixed-length modulation M=8 is the optimum number of levels and it is superior to RLL overall. We also show that M-ary RLL is a practical alternative if stronger coding can be applied to it.
