  • Write element modification control using a galvanic couple
    Patent number: 8029659
    Abstract: A modification rate at a surface of an anode formed on a substrate is controlled. The anode is connected to a cathode comprised of a material having a higher nobility than the anode. An electrically conductive path is established between the anode and the cathode through an electrolyte to induce formation of an oxide layer at the anode surface that is more resistive to modification than the anode.
