Magnetoresistive sensor having low resistivity dual path conductor and optimized magnetic |
摘要 |
A transducing head has a magnetoresistive sensor and a first and a second dual path conductor/magnet structure for providing current to the magnetoresistive sensor and for stabilizing the magnetoresistive sensor. The first and the second dual path conductor/magnet structures are arranged in an abutted-junction configuration on opposite sides of the magnetoresistive sensor. Each of the first and the second dual path conductor/magnet structures has at least one bias layer and at least one conductor layer. Each bias layer is formed upon a bias seed layer positioned over one of the conductor layers. Each bias seed layer is selected to result in the bias layer formed upon it having a coercivity between about 1 kOe and about 5 kOe and an in-plane remnant squareness greater than about 0.8. Most preferably, each of the first and the second dual path conductor/magnet structures is formed of at least two conductor layers interspersed with at least one bias layer.
