Claims
- 1. A magnetic recording head having an air bearing surface, the magnetic recording head comprising:
a writer having a top pole, a shared pole and a conductive coil, the top pole and shared pole separated by a write gap region, the top pole being substantially planar, the shared pole including a recess, at least a portion of the conductive coil positioned in the recess; and an organic insulator positioned in the recess between turns of the conductive coil.
- 2. The magnetic recording head of claim 1, wherein the organic insulator is a cured photoresist.
- 3. The magnetic recording head of claim 1, and further comprising a first insulating layer positioned in the recess over the conductive coil and the organic insulator.
- 4. The magnetic recording head of claim 3, and further comprising a second insulating layer positioned in the recess under the conductive coil and the organic insulator.
- 5. The magnetic recording head of claim 4, wherein the first and the second insulating layers are each one of Al2O3, Si3N4 and SiO2.
- 6. A magnetic recording head having an air bearing surface, the magnetic recording head comprising:
a writer having a top pole, a shared pole and a conductive coil the top pole and shared pole separated by a write gap region adjacent the air bearing surface, the top pole being substantially planar, the shared pole including a recess, at least a portion of the conductive coil positioned in the recess; electrical insulation positioned in the recess and surrounding turns of the conductive coil; and a substantially planar write gap layer overlying the electrical insulation and a portion of the shared pole adjacent the air bearing surface to define the write gap region.
- 7. The magnetic recording head of claim 6 wherein the electrical insulation includes an organic insulator.
- 8. The magnetic recording head of claim 6, wherein the organic insulator is a cured photoresist.
- 9. The magnetic recording head of claim 7, wherein the electrical insulation further includes a first insulating layer positioned in the recess over the conductive coil and the organic insulator.
- 10. The magnetic recording head of claim 9, wherein the electrical insulation further includes a second insulating layer positioned in the recess under the conductive coil and the organic insulator.
- 11. The magnetic recording head of claim 10, wherein the first and the second insulating layers are each one of Al2O3, Si3N4 and SiO2.
- 12. A magnetic recording head having an air bearing surface comprising:
a bottom pole including a bottom pole layer, a magnetic stud and a back gap closer that define a bottom pole recess; a conductive coil having a first coil portion positioned in the bottom pole recess; a filling in the bottom pole recess that insulates the conductive coil; a write gap layer overlying a planar surface defined by the magnetic stud and the filling; and a substantially planar top pole overlying the write gap layer and connected to the back gap closer, the top pole having a top pole tip spaced from the magnetic stud by the write gap layer at the air bearing surface.
