High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small 3-inch (7.6 cm) nickel plate. Up to 196,000 8.5×11 in (22×28 cm) pages of information can be stored onto the plate using a focused ion beam. The image capacity for an HD-Rosetta disc can range from 10,000 to 100,000 images on a 4096 by 4096 pixel x vs. y plane.[1] Similar to hieroglyphics and microfilm, HD-Rosetta is used for preserving information. Norsam Technologies has made HD-Rosetta extremely durable, compared to most archival data devices. It has an estimated longevity of 10,000 years, and it can withstand a minimum of 1000 years.[citation needed] HD-Rosetta has also been used for purposes other than archival. De Beers has currently used HD-Rosetta technology to provide clear marking on diamonds and other gemstones. HD-Rosetta does not require any specific software or operating systems to read the information: the information engraved onto the HD-Rosetta disc is easily accessed with a microscope.[2]
