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, the first end of the second shield being separated from the first end of the first shield by a read gap, the central portion of the second shield being separated from the central portion of the first shield by a distance that is greater than the read gap; 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, the magnetoresistive sensor being a giant 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.
