  • Bilayer shared pole extension for reduced thermal pole tip protrusion
    Patent number: 6876526
    Abstract: A transducing head formed upon a slider has an air bearing surface, a top magnetic pole, a shared magnetic pole, a write via, and a shared pole extension. The write via is positioned opposite the air bearing surface and extends between the top magnetic pole and the shared magnetic pole. The shared pole extension is positioned adjacent the air bearing surface and extends from the shared magnetic pole toward the top magnetic pole. The shared pole extension is separated from the top magnetic pole by a write gap. The shared pole extension is formed of a multilayer having a layer of a first material having a high magnetic moment and a layer a second material having a coefficient of thermal expansion substantially similar to a coefficient of thermal expansion of the slider material.
