Abstract:

A transducing head formed upon a slider has a transducer, an electrical contact layer, a stud electrically connected to the contact layer, and a bond pad electrically connected to the stud. The electrical contact layer is electrically connected to the transducer. The stud is formed of a material having a coefficient of thermal expansion less than about 1.3 times a coefficient of thermal expansion of a slider material forming the slider. The bond pad has a metallic underlayer and a top layer. The metallic underlayer is formed of a material having a coefficient of thermal expansion less than about 1.1 times the coefficient of thermal expansion of the slider material.
