A read/write magnetic head assembly includes an inductive write head and a magnetoresistive (MR) read head. The inductive write head includes first and second magnetic poles, P1 and P2 respectively, which form a magnetic circuit with a write transducing gap. The P1 pole is formed in an integral structure with a wider extending flux shield section. The shield section extends from the lower surface of the P1 layer to define a stepped or staggered configuration. The MR head includes an MR sensor element that is disposed between a lower flux shielding layer and the P1 pole/shield section structure. The narrow width of the P1 pole layer at the write gap region and the extended shield section of the integral P1 pole/shield structure serve to reduce the write fringing field which occurs during the write mode. In this way, the recorded data tracks can be narrowed with a resultant increase in track density.
