  • Abstract
    A correlation between touchdown sensor and head-media spacing signals is established and discussed in this paper. Experiments are performed on commercially available air bearing drives operating at 7200 rpm. The correlation between fly height and the temperature response provides insights on the heat transfer model in head disk interface.
