<p>A read-write magnetic head (12) includes a write transducer disposed side-by-side with a read transducer on a substrate (4). The write transducer includes an inductive coil sandwiched between first and second magnetic poles (28, 30). The read transducer comprises a read sensor disposed between first and second magnetic shields (40, 42). The first and second magnetic shields (40, 42) are electrically insulated from and substantially coplanar with the first and second magnetic poles (28, 30), respectively. The number of material layers in the magnetic head (12) is reduced as the first pole and the first shield can be fabricated simultaneously. Likewise, the second pole and the second shield can be fabricated simultaneously. With a reduced number of layers, the magnetic head (12) poses less of a step coverage problem during manufacture. Moreover, the read transducer can be fabricated prior to the inductive coil without subjecting the read transducer to the high heat process required for the curing of photoresist which surrounds the coil. There are also less thermal and magnetic interferences between the write and read transducers during normal operations. <IMAGE></p> |
