    摘要： A system for poling piezoelectric devices comprises a plurality of thin-film components, a plurality of piezoelectric devices, a poling pad for poling the piezoelectric devices, a plurality of traces, and a plurality of current-limiting elements. The thin-film components are separated by dice lanes to form an array, and the piezoelectric devices are formed on the thin-film components. The traces connect the piezoelectric devices across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric devices, in order to limit current to individual piezoelectric devices that experience current-related failure.

    摘要： Thermal energy is generated within an optical NFT when in operation within a HAMR head. A heat-sink assembly within the HAMR head extracts thermal energy from the optical NFT and transmits the thermal energy via convection to air surrounding the HAMR head, radiation to surfaces adjacent to the HAMR head, and/or conduction to other parts of the HAMR head. The thermal energy generated within the optical NFT is conducted to the heat-sink. An air-bearing surface of the heat-sink convectively transfers at least some of the thermal energy to air passing between the air-bearing surface and a surface of an adjacent magnetic medium. Further, some of the thermal energy may also radiatively transfer from the air-bearing surface to the magnetic medium.

    摘要： A data transducer is used for writing data to a disc and has an air bearing surface. The data transducer also includes a bottom pole and a top pole separated from the bottom pole at the air bearing surface by a write gap. A core is formed between the bottom pole and the top pole and a conductive coil is positioned within the core. The data transducer further includes an insulator conformed to turns of the conductive coil and a core fill deposited within the entire core wherein the core fill is a high-thermal conductivity material. The insulator and core fill dissipate thermal energy away from the conductive coil.
