Abstract: An apparatus comprises a thermal sensor configured to interact with a magnetic recording disk. A head-disk interface is defined between the thermal sensor and the disk. A power supply is coupled to the thermal sensor and configured to supply a bias power to the thermal sensor between a low power and a high power. A processor is coupled to the thermal sensor and configured to determine a slope of a resistance response of the thermal sensor. The processor is further configured to detect a change in the slope relative to a baseline slope. The slope change indicates increased heat sinking between the thermal sensor and the disk due to the presence of contaminant buildup at the head-disk interface.
