Abstract: A method of surface coating a metallic object, including removing substantially all of the existing silver sulfide tarnish if present, ultrasonically cleaning the object with immersion in a solvent, uniformly dispersing selected nanoparticles over the surface of the object by sonicating the object in an ultrasonic bath containing the selected nanoparticles. The invention further includes quickly rinsing the object with solvent upon removal from the ultrasonic bath to inhibit formation of large agglomerates, drying the object with a flow of gas, optically inspecting the object for the presence of agglomeration and applying a barrier layer conformal coating and a protective layer conformal coating.

Abstract: Analog data such as text and images are stored in microscopic analog format on a disk surface capable of maintaining the information for 1000 years or more whereby simple optical magnification will result in one being able to read the information formed therein. For a disk read by backlighting, as with microfiche, a photosensitive material is overlayed on hard metal surface which in turn is formed on a transparent glass or quartz material. A laser beam is focused on certain desired portions of the photosensitive material and the exposed material and underlying hard metal layer etched off to form pits down to the transparent layer corresponding to the analog information. The resulting disk can then be used to produce archival copies and distribution copies using hot embossing or other disclosed techniques.
