A system and method to minimize the contribution of head channel spacing to the negative effects of transverse changes in dimensions of recording media having prerecorded servopositioning tracks. Multiple channels on the recording head are separated into multiple groups of head channels, and each group of heads is independently positioned relative to the pre-written servo tracks. The head comprises an actuator for each pair of head groups. The actuator adjusts the relative spacing between members of the pair in response to position error signals indicating misalignment between the heads and the pre-written servopositioning tracks on the medium.
