Advance pole trim writer with moment P1 and low apex angle

摘要

A magnetoresistive head having improved overwrite performance and a small trackwidth. The magnetoresistive head having a magnetic yoke formed of first and second poles joined at a back gap region and having an opposite write gap region. A pedestal with a top portion constructed of a high saturation moment material is provided on the first pole, limited to the write gap region and spaced from the read element so as to prevent popcorn noise in read sensor. The high moment pedestal is raised above surrounding structure causing the second pole to define a very low apex angle in the write gap region.
