in certain embodiments, an apparatus includes a write pole tip having a top side that has a monotonically decreasing slope that forms a convex profile between a write pole paddle and an air bearing surface. In certain embodiments, an apparatus includes a write pole tip having a first and second top bevel. The first top bevel is at an angle greater than the second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.

Devices including a write pole tip with a convex shape

A non-limiting embodiment of a magnetic writer has at least a write element having a write element tip and a conductive structure adjacent the write element. The conductive structure has at least two conductive elements positioned substantially parallel to one another and separated by an electrically insulating material. Each of the conductive elements carries a time-varying signal to generate an oscillating magnetic field from a displacement current between the two conductive elements, with the oscillating magnetic field being proximate the write element tip and extending parallel to the air bearing surface. A frequency of the oscillating magnetic field is a function of a frequency of the time-varying signal.
