ABSTRACT:
Asymmetry correction for an MR read head in a magnetic recording channel employs an exponential function to correct MR read head asymmetry. The asymmetry correction function has the form ƒASC(y)=y−q(eay+e−ay−2), wherein a is a parameter that can be adjusted for optimal channel performance, and q is an asymmetry correction coefficient.
