Abstract:
A magnetic head according to one embodiment includes a module, the module having both read and write transducers positioned towards a media facing side of the module, wherein the read and write transducers are selected from a group consisting of piggyback read-write transducers, merged read-write transducers, interleaved read and write transducers, and an array of write transducers flanked by servo read transducers; wherein the write transducers include write poles having media facing sides with negative, zero or near-zero recession from a plane extending along the media facing side of a substrate of the module; wherein the read transducers each have at least one shield, wherein a media facing side of the at least one shield is more recessed from the plane than the write poles.
