摘要： A method for measuring the head-disk clearance between a slider and a disk includes measuring a first resistance with a first bias applied to an embedded contact sensor of the slider, measuring a second resistance with a second bias applied to the embedded contact sensor of the slider, and determining the head-disk clearance based at least in part on a difference between the first resistance and the second resistance. A system includes a disk drive, a slider comprising an embedded contact sensor, and circuitry to apply at least two bias voltages to the embedded contact sensor, measure at least two resistances of the embedded contact sensor based on the application of the at least two bias voltages, and to determine the head-disk clearance based at least in part on a difference between the at least two resistances.
