Multilevel run-length-limited (ML-RLL) recording technology could be employed to increase the capacity of the read-only disc without changing optical and mechanical units. In this paper, the tracking error signal (TES) of differential phase detection (DPD) for ML-RLL digital versatile disk (DVD) read-only disk driver is analyzed in both theoretical and experimental way, the uniformity and symmetry of which are worse than that of the DVD read-only disk driver. The variation of peak to peak (PP) value distribution of the DPD signal in open loop of ML-RLL DVD read-only disk driver is about 2.6 times of that of the conventional DVD driver while the asymmetry is about 4 times. It is predicted that some improvements of the tracking servo system are needed in ML-RLL system.
