Thermoelectric voltage-based differential contact sensor
Abstract:
Approaches for a hard-disk drive (HDD) comprising a head slider comprising a thermoelectric embedded contact sensor. The thermoelectric embedded contact sensor may comprise a first and second conductive lead and a metallic component. The metallic component has a different Seebeck coefficient than the first and second conductive leads. A thermoelectric voltage across the metallic component is used to measure the distance between a head slider and a magnetic-recording disk without supplying an electrical current from a hard-disk drive to either of the first conductive lead or the second conductive lead.
