Segmented magnetic recording write head for detection-based servo pattern writing
An apparatus-implemented method according to one embodiment includes passing a magnetic recording tape over a plurality of modules having write transducers, and causing the write transducers to write predefined patterns of magnetic bars on the magnetic recording tape. Associated pairs of the write transducers are aligned along an intended direction of tape travel thereacross. Planes of deposition of write gaps of the write transducers in each associated pair are oriented at an angle of greater than 4 degrees relative to each other. A timing of writing of each write transducer is controlled such that resulting patterns of magnetic bars written by each associated pair are offset from one another in the intended direction of tape travel.
