Abstract
The signal source generates a signal of a frequency higher than the vibration frequency of the slider of the hard disk drive, and supplies it to one end of the slider and the disk of the hard disk drive. The detector detects a signal output from the other end of the slider and the disk, and outputs a change in the capacitance between the slider and the disk as a voltage when the hard disk drive receives an impact.
