Abstract
An apparatus according to one embodiment includes a first module having a plurality of first write transducers, and a plurality of second modules each having a second write transducer. Planes of deposition of write gaps of the second write transducers are oriented at an angle of greater than 4 degrees relative to planes of deposition of write gaps of the first write transducers. An apparatus according to another embodiment includes a plurality of first modules each having a first write transducer, and a plurality of second modules each having a second write transducer. Planes of deposition of write gaps of the second write transducers are oriented at an angle of greater than 4 degrees relative to planes of deposition of write gaps of the first write transducers.
