A magnetoresistive sensor having an improved read sensitivity function which remains relatively stable in response to variations in lapping. The magnetoresistive sensor includes a magnetoresistive element, a first electrical contact and a second electrical contact. During lapping, the boundaries between the electrical contacts and the magnetoresistive element, and therefore the active region of the magnetoresistive element, remain relatively constant in a lateral direction across the magnetoresistive sensor. This provides a relatively insensitive read sensitivity function within a predetermined lapping tolerance range.
