Claim Text:
1. A data access system, the system comprising: a head including a first read sensor, a second read sensor and a third read sensor; a first interpolator circuit operable to modify the phase of a first data set derived from the first sensor based upon a first phase feedback to yield a first modified data set; a second interpolator circuit operable to modify the phase of a second data set derived from the second sensor based upon the first phase feedback to yield a second modified data set; a third interpolator circuit operable to modify the phase of the second data set derived from the second sensor based upon a second phase feedback to yield a third modified data set; a fourth interpolator circuit operable to modify the phase of the third data set derived from the third sensor based upon the second phase feedback to yield a fourth modified data set; a first offset determination circuit operable to provide the first phase feedback based upon a combination of the first modified data set and the second modified data set; and a second offset determination circuit operable to provide the second phase feedback based upon a combination of the third modified data set and the fourth modified data set.
