Abstract
In a magnetoresistive transducer, a conductor configuration in which magnetic fields in the conductors are oriented in the same direction to provide symmetric track profiles and improved track edge response. Conductor area at the transducer air bearing surface is also minimized to eliminate shorting and improve device yield and reliability. In one embodiment of the invention, inductive pickup is minimized by limiting the active width of magnetoresistive sensing elements through conductor placement. Another embodiment of the invention, useful for applications involving dual stripe magnetoresistive transducers, minimizes inductive pickup by providing relatively large conductors for each magnetoresistive stripe, arranged in parallel with each other and coupled differentially to cancel inductive pickup through common mode rejection.
