Abstract :
The new negative pressure slider called NNP slider has been developed for the attainment of high density recording in magnetic disk drives. The NNP slider has high stiffness and a very small flying height of 0.1 μm independent of the disk velocity. And in using an actual disk(a sputtered disk), the NNP slider can follow the vertical run-out of the disk and fly stably, even though the flying height may fluctuate due to the undulation or roughness of the disk. Therefore, crash phenomena do not occur. The stable flying of the NNP slider can bring out the best properties of the sputtered disks.
