Write Head Design for Control of Transition Curvature in Heat-Assisted Magnetic Recording
IEEE TRANSACTIONS ON MAGNETICS(2024)
摘要
Transition curvature in heat-assisted magnetic recording (HAMR) can limit the linear recording density. In this work, we propose a write-head design that can reduce transition curvature. The split-pole write head incorporates a nanocoil that generates a field in the opposite direction to the main pole excited by the head coil winding, allowing transition curvature to be greatly reduced.
