Density improvements in digital magnetic recording by decision feedback equalization

J.W.M. Bergmans

Abstract

The information density improvements are estimated that are feasible by applying decision feedback equalization instead of conventional linear equalization in digital magnetic recording systems, with differentiating playback heads. Significant improvements are shown to be within reach for an important class of transmission codes.
