Magnetic write heads with bi-layer wrap around shields having dissimilar shield layer widths |
摘要 |
Magnetic write heads and corresponding fabrication methods for bi-layer wrap around shields resulting in dissimilar shield layer widths are disclosed. A gap structure is formed around a main write pole for a magnetic write head. A wrap around shield for the main write pole is fabricated to include a first magnetic layer proximate to the main write pole and a second magnetic layer on the first magnetic layer. A width of the first magnetic layer is less than the width of the second magnetic layer, and back edges of the first and second magnetic layers are coplanar. Further, a throat height of the wrap around shield is maintained between the first and the second magnetic layers because their back edges are coplanar. |
