Abstract
Embodiments of the present invention determine the offset of a first burst of a burst pair from a centerline. This can be used to determine the desired offset position for a second burst of the burst pair. The target signal to provided the data storage unit for writing the second burst can take into account the transfer function of the controller and the physical plant so as to more accurately write at the desired offset position.
