METHOD OF DETECTING THE TOUCH-DOWN OF A HEAD, METHOD OF ADJUSTING A HEAD FLYING HEIGHT USING THE METHOD OF DETECTING THE TOUCH-DOWN OF THE HEAD, AND DISK DRIVE USING THE METHOD OF DETECTING THE TOUCH-DOWN OF THE HEAD
METHOD OF DETECTING THE TOUCH-DOWN OF A HEAD, METHOD OF ADJUSTING A HEAD FLYING HEIGHT USING THE METHOD OF DETECTING THE TOUCH-DOWN OF THE HEAD, AND DISK DRIVE USING THE METHOD OF DETECTING THE TOUCH-DOWN OF THE HEAD
A method of detecting a touch-down of a head in a disk drive, a method of adjusting a head flying height by using the method of detecting a touch-down of a head, and a disk drive using the method of detecting a touch-down of a head detect a change of an electrical characteristic of a sensor installed in a slider, wherein the electrical characteristic changes according to temperature; and determines that the head flying height reached a touch-down flying height if the detected change of the electrical characteristic satisfies a threshold condition.
