HD-Rosetta HD-Rosetta High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small nickel plate. Up to 196,000 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. 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
