ABSTRACT:
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.
