ABSTRACT:
A magnetic write head having a write coil configured to dissipate heat away from the write head to minimize thermal protrusion. The write coil is formed as a helical coil having upper and lower leads that are connected by electrically conductive studs formed therebetween. The first and leads extend beyond the studs to form heat conducting fins that conduct heat away from the write head where it can be dissipated into surrounding structure.
