UNSHIELDED HORIZONTAL MAGNETORESISTIVE HEAD AND METHOD OF FABRICATING SAME

摘要

An unshielded horizontal magnetoresistive head (1) for magnetic sensing and reading devices. The horizontal unshielded magnetoresistive head (1) is comprised of two magnetoresistive elements (2) separated by a gap (10), and a conductive cross member (3) which electrically connects the magnetoresistive elements (2) together and to a common electrical point such as system ground (4). A differential voltage sensing circuit (35) is connected across the magnetoresistive elements (2) for sensing voltage variations when magnetic data is sensed by the head (1). The present invention further facilitates a more simplified fabrication process which results in cost savings and more efficient fabrication methods and procedures.
