Skew-tolerant reader configurations using cross-track profiles for array-reader based magnetic recording
Abstract:
A method for enhancing read performance in an ARMR system includes: obtaining a first reader offset profile corresponding to a first reader of a multi-reader array head in the ARMR system; obtaining at least a second reader offset profile corresponding to at least a second reader of the multi-reader array head in the ARMR system; combining the first and second reader offset profiles to generate a combined reader offset profile; and controlling a location of the multi-reader array head in the ARMR system relative to at least one target track associated with a magnetic storage medium to be read as a function of a peak amplitude of the combined reader offset profile.
