Patent ID: 6949833

Claim:
A magnetic head comprising: (a) a substrate comprising a top surface having a first and a second portion; (b) an etched dielectric layer comprising sidewalls and an upper surface, wherein said etched dielectric layer is positioned upon said first portion of said top surface of said substrate but not positioned upon said second portion of said top surface of said substrate, wherein said etched dielectric layer has a thickness equal to v, and wherein said second portion of said top surface of said substrate has a width equal to x; (c) at least one monolayer, wherein said at least one monolayer is positioned upon said upper surface of said etched dielectric layer, said sidewalls of said etched dielectric layer, and said second portion of said top surface of said substrate, and said at least one monolayer has a thickness of y; (d) a trench, wherein said trench is formed by said at least one monolayer, and said trench has a width equal to x−2y; and (e) a magnetic write pole positioned within the trench.
