Abstract
According to one embodiment, a magnetic data system includes a magnetic disk medium, a magnetic head having a writer element and/or a reader element, an exothermic resistor element for thermal fly-height control (TFC), a contact detection sensor having a resistor element and at least one contact detection electrode, and an insulating film on a medium facing side of the magnetic head to protect the contact detection sensor, the insulating film having a thickness greater than the contact detection electrode, a drive mechanism for passing the magnetic disk medium over the magnetic head, and a controller electrically coupled to the magnetic head for controlling operation of the magnetic head, wherein the controller adjusts magnetic spacing between the magnetic head and the magnetic disk medium via thermal distortion of the exothermic resistor element. The contact detection sensor may be used as a second TFC resistor element.
