Mechanism to shift the head span of a tape head at a wafer level

Provided are a magnetic tape head, a magnetic tape drive, and a computational device in which the magnetic tape head is comprised of a plurality of modules comprising reader modules and writer modules, and a plurality of elements, wherein a total of shifts of selected elements of the plurality of elements that are shifted add up to a desired total shift to realign the plurality of modules, such that a median head span of each module type matches as close as possible to a desired value of a head span for all module types including the reader modules and the writer modules and wherein the head span is shifted at a wafer level.
