Abstract
A transducing head writer comprising a write pole having write pole tip, a yoke disposed on the write pole at a location that is recessed from the write pole tip, and a bridge feature disposed on the write pole between the yoke and the write pole tip, where the bridge feature has a geometry that is larger at a recessed end adjacent to the yoke compared to a proximate end adjacent to the write pole tip.
Claims20
A device comprising:
- a medium;
- and
- a transducing head writer comprising:
- a write pole having a trailing surface and a write pole tip;
- a yoke disposed on the trailing surface of the write pole, with respect to a direction of motion of the medium, at a location that is recessed from the write pole tip;
- and
- a bridge feature disposed on the trailing surface of the write pole between the yoke and the write pole tip, wherein the bridge feature has a geometry that is larger at a recessed end adjacent to the yoke compared to a proximate end adjacent to the write pole tip.

A device comprising:
- a medium;
- and
- a transducing head writer comprising:
- a write pole having a trailing surface and a write pole tip;
- a yoke disposed on the trailing surface of the write pole, with respect to a direction of motion of the medium, at a location that is recessed along an axis from the write pole tip;
- and
- a bridge feature disposed on the trailing surface of the write pole, wherein the bridge feature comprises:
- a recessed end that is adjacent to the yoke;
- a proximate end that is adjacent to the write pole tip;
- a first cross-sectional area orthogonal to the axis at the recessed end;
- and
- a second cross-sectional area orthogonal to the axis at the proximate end, wherein the first cross-sectional area is greater than the second cross-sectional area.
