Devices including a write pole tip with a convex shape
View Patent ↗in certain embodiments, an apparatus includes a write pole tip having a top side that has a monotonically decreasing slope that forms a convex profile between a write pole paddle and an air bearing surface. In certain embodiments, an apparatus includes a write pole tip having a first and second top bevel. The first top bevel is at an angle greater than the second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.
1. An apparatus comprising:
a write pole tip having a first top bevel and a second top bevel, wherein the first top bevel is at an angle greater than the second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.
2. The apparatus of claim 1 , further comprising:
a front shield positioned adjacent to the write pole tip and having an angle substantially the same as the first top bevel angle.
3. The apparatus of claim 1 , wherein the write pole tip further comprises a bottom bevel.
4. The apparatus of claim 1 , wherein the first top bevel is positioned closer to the air bearing surface than the second top bevel.
5. The apparatus of claim 1 , wherein the write pole tip further comprises greater than two top bevels.
6. An apparatus comprising:
a write pole tip having a top side that has a monotonically decreasing slope forming a convex profile between a write pole paddle and an air bearing surface.
7. The apparatus of claim 6 , wherein the convex profile comprises at least two bevels.
8. The apparatus of claim 6 , wherein a first top bevel is at an angle greater than a second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.
9. The apparatus of claim 6 , wherein the convex profile continuously decreases in slope.
10. The apparatus of claim C, wherein the top side faces a front shield positioned adjacent to the write pole.
11. The apparatus of claim 6 , wherein the write pole tip includes a bottom bevel.
12. An apparatus comprising:
a write pole tip having a first top bevel and a second top bevel, wherein the first top bevel is at an angle different than the second top bevel with respect to a plane perpendicular to air bearing surface of the write pole tip.
13. The apparatus of claim 12 , further comprising:
a front shield positioned adjacent to the write tip and having an angle substantially the same as the first top bevel angle.
14. The apparatus of claim 12 , wherein the write pole tip further comprises greater than two top bevels.
15. The apparatus of claim 12 , wherein the write pole tip further comprises a bottom bevel.
16. The apparatus of claim 12 , wherein the write pole tip further comprises greater than two top bevels.
