Patent ID: 7012789

Claim:
A magnetic recording head comprising: a merged magnetoresistive read head/inductive write head, said write head having a write gap between an upper High saturation Moment Material (HMM) pole and a composite shared pole, said read head being located between a shield layer and said composite shared pole, said composite shared pole consisting of a Permalloy-Like Material (PLM) layer, said PLM layer having a width substantially greater than width “W”, said PLM layer being laminated with a HMM lower pole layer with tapered sidewalls, a joint between said HMM lower pole layer and said PLM layer with said HMM lower pole layer having said width “W” at said joint with said PLM layer and having a width “N” adjacent to said write gap, said shield layer and the HMM lower pole layer being substantially wider than said width “W”, said write head having said upper HMM pole made of HMM material having said narrow width “N”, and said width “W” is substantially greater than said width “N”.
