description A symmetrical read element circuit for reducing electrical and magnetic noise using signal processing, such as a differential preamplifier. The circuits are symmetrically created on both sides of the read element so that the noise is balanced on both leads of the sensor element allowing substantial noise reduction by the signal processing. That is, the present invention provides symmetrical leads and pads designed for equal noise pickup, and for cancellation of the balanced noise.
