giraffe–attack: polyglotweekly: ultrafacts: The Rosetta Disk...




The Rosetta Disk fits in the palm of your hand, yet it contains thousands of pages of information on over 1,500 human languages. The pages are microscopically etched and then electroformed in solid nickel, a process that raises the text very slightly - about 100 nanometers - off of the surface of the disk. Each page is only 400 microns across - about the width of 5 human hairs - and can be read through a microscope at 650X as clearly as you would from print in a book. Individual pages are visible at a much lower magnification of 100X.

The pictures above is from an interactive version of the Rosetta Disk that gives you an idea what it is like to browse the contents of an actual Rosetta Disk through a microscope. The interactive version shows the first prototype design of the Rosetta Disk which has two sides.
