Abstract

A non linear magnetoresistive sensor having a magnetoresistive strip with no transverse biasing (either permanent or current) such that the sensor is operated in its non linear mode. The sensor is useful in its non linear mode to determine the location of pulse peaks from encoded data from a medium by differentiating and determining the zero crossings of the detected signal.
