Abstract:
Devices and methods are provided for heat-assisted magnetic recording (HAMR). In an illustrative example, a device includes a magnetic write pole having a convex pole tip; a magnetic opposing pole longitudinally displaced from the magnetic write pole; and a thermal-source component disposed proximate to the magnetic write pole and comprising a laterally elongated thermal-source peg disposed proximate to the convex pole tip.
