摘要： A method and system for determining localized contact potential voltages and localized clearance data between a slider body and a hard disk of a hard disk drive. In embodiments of the present invention, a plurality of direct current (DC) pulses are applied between said slider body and a discreet location of the hard disk. In embodiments of the present invention, the discreet location of the hard disk comprises a portion of a data track of the hard disk. In embodiments of the present invention, a variation in the clearance of the slider body is determined when a given voltage is applied. Furthermore, a first set of DC pulses has a positive/negative bias while a second set of DC pulses has a negative/positive bias. The voltage of the sets of DC pulses is increased until a contact between the slider body and the hard disk is detected.

摘要： A method and system for measuring slider body clearance in a hard disk drive using positive and negative electrical pulses. In one embodiment, at least one positive direct current (DC) pulse is applied between a slider body and a hard disk of the hard disk drive. Furthermore, at least one negative direct current (DC) pulse is applied between the slider body and the hard disk. A contact potential voltage between said slider body and said hard disk is then determined in response to applying the at least one positive direct current (DC) pulse and the at least one negative direct current (DC) pulse.
