Abstract:
A method of storing at least one color image in a durable medium, comprising the steps of:(a) placing a crystalline or highly polished durable medium having a substantially flat target surface within a vacuum environment; (b) producing a computer data file adapted to operate a computer-controlled, focused ion beam to form an elliptical beam spot on the target surface to mill elliptical, blazed pits into the durable medium; and (c) exposing the target surface of the durable medium to the ion beam, the ion beam being controlled by software utilizing the computer data file, whereby elliptical blazed pits are milled into the durable medium at predetermined locations, thereby transforming the durable medium into a durable storage medium having at least one stored color image retrievable by illuminating the durable storage medium with polychromatic light.
