Abstract

An apparatus, according to one embodiment, includes: an array of write transducers. Each of the write transducers include: a first write pole having a pole tip extending from a media facing side of the first write pole, and a second write pole having a pole tip extending from a media facing side of the second write pole. Each of the write transducers also include a nonmagnetic write gap between the pole tips of the write poles, and a first high moment layer between the write gap and the pole tip of the second write pole. The first high moment layer further includes a higher magnetic moment than a magnetic moment of the pole tip of the second write pole. Other systems, methods, and computer program products are described in additional embodiments.
