Abstract:
A magnetoresistive head for reading data from a recording media comprising:a first shield having a first end, a central portion and a second end, the first end being closer to the recording media during use than the second end; a second shield having a first end, a central portion, and a second end, the first end of the second shield being closer to the recording media during use than the second end of the second shield; a magnetoresistive sensor disposed between the first shield and the second shield, the magnetoresistive sensor having a front end and a back end, the front end of the magnetoresistive sensor being closer to the recording media during use than the back end, the front end of the magnetoresistive sensor being electrically coupled with the first end of the first shield or the first end of the second shield; at least one insulating bias layer magnetically coupled to the magnetoresistive sensor, the at least one insulating bias layer for magnetically biasing at least a portion of the magnetoresistive sensor; and a lead electrically coupled with the back end of the magnetoresistive sensor; wherein current is driven through the magnetoresistive sensor in a direction substantially perpendicular to the recording media during use; and wherein the front end of the magnetoresistive sensor is coupled with the first end of the first shield using a conductor, the conductor including a first nonmagnetic layer and a second magnetic layer.
