Paper Abstract
Multi-level run-length-limited (ML-RLL) modulation on optical storage channels is a promising method to increase
the recording density effectively. In this paper, some experimental results of 4-level RLL modulation on
digital versatile disc (DVD) read-only discs are firstly presented. A new DC-free 4-ary RLL (2, 8) code with
code rate of 8/10 (bits/symbol) is designed, and partial-response maximum-likelihood (PRML) detection is used
to evaluate the bit error rate (BER) performance of multi-level readout signals. Experimental and simulation
results show the feasibility of 4-level RLL modulation on DVD channels.
