In 2002,IBM scientists used innovative nanotechnology to demonstrate a data-storage densityof a trillion bits per square inch—20 timeshigher than the most-dense magnetic storage available today. IBM achievedremarkable density, enough to store 25 million printed textbook pages on a surface thesize of a postage stamp.18
