An apparatus includes a head having at least three pairs of modules, each module having an array of transducers and at least one servo transducer. The axes of the arrays are oriented about parallel to each other. Of each pair of modules, the array of a first module is offset from the array of a second module in a direction parallel to the axis of the array of the second module. All of the transducers of each first module are positioned on a first side of an imaginary line oriented in the intended direction of tape travel, all of the transducers of each second module are positioned on a second side of the imaginary line. A first pair of modules and a third pair of modules have a same first function, and a second pair of modules has a second function, the first function and the second function are different.
