An apparatus-implemented method according to one embodiment includes passing a magnetic recording tape over a plurality of modules having write transducers. Associated pairs of the write transducers are aligned along an intended direction of tape travel thereacross, and planes of deposition of the write gaps of the write transducers in each associated pair are oriented at an angle of greater than 4 degrees relative to each other. The method also includes causing the write transducers to write predefined patterns of magnetic bars on the magnetic recording tape.
