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.
Claims18
An apparatus, comprising:
- a module having a substrate, read and write transducers positioned toward a media facing side of the module, and a closure;
- 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 the substrate of the module;
- wherein the read transducers each have two shields, wherein media facing sides of the shields are more recessed from the plane than the write poles;
- wherein the media facing sides of the shields are recessed a same amount from the plane.
An apparatus, comprising:
- a substrate having a media facing side;
- and
- an array of read and write transducers;
- wherein the write transducers include write poles having media facing sides;
- wherein the read transducers each have two shields, wherein the media facing sides of the shields are recessed a same amount from a plane extending along the media facing side of the substrate.
An apparatus, comprising:
- a pair of read and write transducers above a substrate;
- wherein the read transducer has two shields, wherein media facing sides of the shields are more recessed from a plane extending along the media facing side of the substrate than media facing sides of write poles of the write transducer,
- wherein the media facing sides of the shields are recessed a same amount from the plane.
