We propose noise-predictive maximum-likelihood (NPML) detection with a pattern-dependent distortion canceller (PDDC) to cancel nonlinear distortion. NPML detection and NPML/PDDC detection were applied to a Blu-ray disc with a capacity of 27 Gbytes. The detection performance was investigated. And the results are reported. Both the NPML detector and the NPML/PDDC detector lower bit error rate (BER), and improve the radial-tilt margin and spherical-aberration margin. Only the NPML/PDDC detector could improve tangential-tilt margin, however.
