The traditional approach to this problem was to spatially modulate a laser beam with an image of ~one million bits ... we explored an alternative approach extnending current optical disk technologies.

Using 3D storage techniques, scientists at the University of Shanghai for Science and Technology developed an optical disk capable of accommodating 1.6 petabits of data (that's 1.6 million gigabits).
