Abstract
The performances of various data detectors, including the maximum likelihood sequence detector (MLSD), are analyzed as a function of media thickness and run-length limited (RLL) code d-constraint. The analysis includes the variation of pulse width and magnetic transition width with media thickness. Performance is calculated in the presence of non-linear partial erasure, or transition amplitude reduction, which changes with media thickness. The RLL code d-constraint effects the media non-linearity and detector processing gain. The results presented predict an optimum media thickness for a given detector and show the relative performance of different detectors and RLL d-constraints.
