Abstract:
An apparatus according to one embodiment includes a module having a substrate, read and write transducers positioned towards a media facing side of the module, and a closure. 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. The read transducers each have two shields. Media facing sides of the two shields are recessed a same amount from the plane, and are more recessed from the plane than the write poles.
