Abstract
An unshielded horizontal magnetoresistive head for magnetic sensing and reading devices. The horizontal unshielded magnetoresistive head is comprised of two magnetoresistive elements separated by a gap and a conductive cross member which electrically connects the magnetoresistive elements together and to a common electrical point such as system ground. A differential voltage sensing circuit is connected across the magnetoresistive elements for sensing voltage variations when magnetic data is sensed by the head. The present invention further facilitates a more simplified fabrication process which results in cost savings and more efficient fabrication methods and procedures.
