Abstract

Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.
