ABSTRACT:
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.
