摘要:
An extraordinary magnetoresistive sensor having optimal magnetic sensitivity capable of reading a very narrow and short magnetic bit. The sensor includes a layer of semiconductor layer and a layer of electrically conductive material. The first and second leads are electrically connected with an edge of the semiconductor material, one of the leads being located a distance inward from an end of the sensor. The sensor also includes first and second voltage leads, located on either side of and close to one of the current leads.
