The flying characteristics performance of this novel femto slider is relatively stable over different radii. This optimized slider achieved a flying height of 3 nm, with variation of about 0.2 nm. The variations for pitch and roll values are 6 μrad and 0.9 μrad respectively. In the studies for the effect of side rail on flying characteristics, it was found that there exists transition of pitch value when the side rail is located very close to the leading edge. The modulation of flying height reduces greatly when the areas of double shallow steps increase.
