Abstract
A read head assembly senses data recorded on tracks of a moving magnetic media. The read head includes a magnetoresistive sensor element for sensing data, and a circuit connected to the sensor element. The circuit is used to electrically activate the sensor element and to monitor the voltage across an active sensing portion of the sensor element which is representative of the data. However, the circuit accomplishes this function without creating longitudinal magnetic fields near the active sensing portion. This reduces a source of magnetic instability and enhances the ability of the sensor element to read data from the track of the moving magnetic media, regardless of the width of the track.
