摘要： A giant magnetoresistance (GMR) head for magnetic storage systems, the GMR head having a free layer with improved soft magnetic properties while retaining giant magnetoresistance (GMR) effects. The free layer comprises an alloy comprising Cox, Fey, and Cuz, wherein x, y, and z represent the atomic weight percentage of Co, Fe, and Cu, respectively.

摘要： A lead overlay magnetic sensor for use in a disk drive is provided having a protective cap layer disposed between the electrical leads and the sensor. The protective cap layer is preferably formed from ruthenium, rhodium, or other suitable material. The sensors thus formed have low resistance between the electrical leads and the sensor and also have well defined magnetic trackwidths.
