Abstract

An assembly including a capacitive height sensor and a conditioning circuit. The capacitive height sensor detects capacitance between a read/write head and a disk surface to monitor variances in a flying height. To bring about a measurement voltage between the capacitive height sensor and the disk surface, the conditioning circuit supplies a drive current to the capacitive height sensor. The conditioning circuit ceases flowing the drive current to the capacitive height sensor upon detecting that the measurement voltage is greater than a high threshold, and commences flowing the drive current to the capacitive height sensor upon detecting that the measurement voltage is less than a low threshold.
