ABSTRACT:
A method of detecting contact between a transducing head-carrying slider and a rotatable disc is performed by applying an electrostatic voltage between the slider and the disc and monitoring current flow across an interface between the slider and the disc. The monitored current flow across the interface between the slider and the disc is analyzed to detect contact between the slider and the disc.
