Abstract
A method for optimizing data transfer performance in a disc drive through selection of optimal reader/writer offsets and write fault thresholds. An initial offset for a selected track is determined as the radial distance between read and write elements of a head as the head is positioned adjacent a selected track. Asymmetric write fault thresholds are selected on opposing sides of the center of the selected track in relation to the ability of the read element to successfully recover data written to the track. An adjustment value is determined in relation to the asymmetry of the write fault thresholds, and the adjustment value is used to modify the initial offset to form a final offset, as well as to make the write fault thresholds symmetric about the center of the track.
