DEVICES INCLUDING SHAPED WRITE COILS
In certain embodiments, a head includes a write coil having multiple coil turns. A portion of the multiple coil turns are positioned near an air bearing surface and form a v- or u-shape. In certain embodiments, a head includes a write coil having multiple coil turns. The coil turns closets to an air bearing surface are tapered.
1 . A head comprising:
a write coil having multiple coil turns, wherein a portion of the multiple coil turns are positioned near an air bearing surface and form a v-shape.
2 . The head of claim 1 , wherein the write coil is a helical coil configuration.
3 . The head of claim 1 , wherein the write coil is a planar coil configuration.
4 . The head of claim 1 , wherein the write coil is positioned near a writer.
5 . The head of claim 1 , wherein the write coil is positioned near a reader.
6 . The head of claim 1 , wherein a coil turn closest to the air bearing surface has a flat section adjacent the air bearing surface.
7 . The head of claim 1 , wherein the write coil is tapered to form the v-shape.
8 . The head of claim 1 , wherein the v-shape induces a narrow protrusion profile.
9 . A head comprising:
a write coil having multiple coil turns in a planar coil configuration wherein a portion of the multiple coil turns are positioned near an air bearing surface and form a u-shape.
10 . The head of claim 9 , wherein a coil turn closest to the air bearing surface has a flat section adjacent the air bearing surface.
