摘要：

Transition curvature in heat-assisted magnetic recording can limit the linear recording density. In this work we propose a write head design which can reduce transition curvature. The split-pole write head incorporates a nano coil which generates a field in the opposite direction to the main pole excited by the head coil winding, allowing transition curvature to be controlled.
