A technique for the measurement of in-plane thermal conductivity of the thin-film superlattice structure in the giant magnetoresistance (GMR) head for data storage systems was proposed. The film was deposited on a silicon dioxide layer of thickness near 1 micron which acted as a thermal barrier. The maximum measurement sensitivity was achieved through the optimized geometric design of the structure from the sensitivity analysis. The results show that the in-plane thermal conductivity of the thin film overlayer can be extracted by comparing the measured average temperature rise in metal bridge.
