A read/write magnetic head assembly includes an inductive write head (42,44) and a magnetoresistive (MR) read head (14,26). The inductive write head (42,44) includes first and second magnetic poles, P1 (42) and P2 (48) respectively, which form a magnetic circuit with a write transducing gap. The P1 pole (42) is formed in an integral structure with a wider extending flux shield section (44). The shield section (44) extends from the lower surface of the P1 layer to define a stepped or staggered configuration. The MR head (14,26) includes an MR sensor element (26) that is disposed between a lower flux shielding layer (22) and the P1 pole/shield section structure (42,44). The narrow width of the P1 pole layer at the write gap region and the extended shield section (44) of the integral P1 pole/shield structure (42,44) serve to reduce the write fringing field which occurs during this write mode. In this way, the recorded data tracks can be narrowed with a resultant increase in track density. <IMAGE> |
