Abstract: A write head having a main pole having a pole tip proximate an air bearing surface (ABS), the main pole having a leading side and a trailing side. The write head also includes a yoke having a yoke tip recessed from the ABS, and a helical coil wrapped around the main pole and the yoke. The helical coil has a first turn with its front edge at least substantially aligned with the yoke tip.

Abstract: A data writer may be generally configured at least with a write pole that has a pole sidewall and a continuous first taper angle connecting leading and trailing edges. The write pole can be positioned adjacent to a side shield that is configured with first and second shield sidewalls tapered to a shield tip that is the closest point between the write pole and side shield.

Abstract: A magnetoresistive sensor is generally disclosed. Various embodiments of a sensor can have at least a trilayer sensor stack biased with a back biasing magnet adjacent a back of the trilayer sensor. The back biasing magnet, the trilayer sensor stack, or both have substantially trapezoidal shapes to enhance the biasing field and to minimize noise.
