Paper Abstract

As linear recording density of optical discs increases, the channel non-linearity grows larger. And narrowing of track pitch also makes the read-out signals affected by large crosstalk from adjacent tracks. These non-linearity and crosstalk degrade the performance of the disc read-out systems. So we need to design equalizers and detecting methods - especially MLSD(Maximum Likelihood Sequence Detector) - considering those deteriorating factors.
