ABSTRACT:
In a dual stripe magnetoresistive transducer a unique conductor configuration is provided that allows close spacing of the two magnetoresistive stripes while providing a nearly identical topography for each of the stripes. A first conductor is arranged on a transducer substrate with an associated magnetoresistive stripe oriented directly above the conductor. A second magnetoresistive stripe is arranged above the first stripe. The second MR stripe, in turn, has an associated conductor oriented above it such that the two stripes may be brought close together, separated only by a thin dielectric layer.
