Abstract:
An apparatus, according to one embodiment, includes: an array of write transducers, each write transducer having: a first write pole having a pole tip extending from a media facing side of the first write pole, a second write pole having a pole tip extending from a media facing side of the second write pole, a nonmagnetic write gap between the pole tips of the write poles, and a high moment layer between the write gap and the pole tip of the second write pole. The high moment layer has a higher magnetic moment than a magnetic moment of the pole tip of the second write pole. Moreover, the high moment layer protrudes beyond a plane extending along a media facing side of the second pole tip. Other systems, methods, and computer program products are described in additional embodiments.
