IBM and Fuji Photo have come up with a way to put 6.67 billion bits of data in a square inch of tape. The image on the right is centered on a single track of data, with bits measuring 15 microns wide and 0.1 microns long. In the center of the left-hand image, are six tracks of data with bits measuring 1.5 microns wide and 0.06 microns long.
