Millipede is a highly parallel scanning probe based data storage that has real storage densities far beyond super-paramagnetic limits and data rates comparable to today's magnetic recording. At the first glance, millipede looks like a conventional 14 X 7 mm 2 silicon chip. Mounted at the centre of the chip is a miniature two-dimensional array of 1024 'v'-shaped cantilevered arms that are 70 µm long and 0.5 µm thick. A nano-sharp fang-like tip, only 20 nm in diameter, hangs from the apex of each cantilever. The multiplex drivers allow addressing of each tip individually. Beneath the cantilever array, is a thin layer of polymer film deposited on a movable, three-axis silicon table. The 2-D AFM cantilever array storage technique called "millipede" is based on a mechanical parallel x/y scanning of either the entire cantilever array chip or the storage medium.
