| Zusammenfassung: | A transducing head has a magnetoresistive sensor and first and second permanent magnet bias elements for providing longitudinal bias to the magnetoresistive sensor. The first and second permanent magnet bias elements are arranged on opposite sides of the magnetoresistive sensor and recessed a distance away from the magnetoresistive sensor. The transducing head of the present invention achieves increased read sensitivity by recessing the first and second permanent magnet bias elements away from the magnetoresistive sensor. |
