Once high density and high data rate can be achieved by engineering, tip/media wear needs to be kept to minimum to preserve the high performance R/W. Nanochip found a way to maintain the tip/media wear to functional level even when the tip is traveled over the media for a distance of few kilometers with a 1 cm/s scanning speed. In Figure 5, a tip was able to write a 25 nm dot after scanning in contact with a PZT media for ~5 km with a speed of 1 cm/s. The tip was loaded with the normal force <100 nN.
