ABSTRACT:
A method for reducing Barkhausen noise in dual stripe magnetoresistive recording heads. The topography of the bottom conductor is controlled, specifically the conductor sidewall angle at the edge of the track is defined to be less than 45.degree. from the substrate plane. Restricting the conductor sidewall profile in this manner eliminates sources of magnetic domain nucleation.
