To achieve areal density of 1 Tb/in squared in the next generation hard disk drive (HDD), the slider has to fly at a height of 3-4 nanometers above the disk surface. To obtain the required accuracy of track seeking and following, the same slider may have to possess capability of in-situ flying height (FH) measurement. A new slider has been proposed and designed with in-situ measurement capability of flying height and mechanical impedance of air bearing.
