ABSTRACT:
A method for following and reading data from a corresponding track on a magnetic disk has two embodiments. Under the first embodiment, an on-track offset value is adjusted upwardly and downwardly in an alternating manner, wherein each successive adjustment increases or decreases by a predetermined step value. Under the second embodiment, maximum and minimum values for the on-track offset value are determined by incrementing the on-track offset value upwardly and downwardly, respectively, an average value based on these maximum and minimum on-track offset values is computed, and the average value is designated as an initial on-track offset value.
