Using the same 3D optical data storage technology as the fluorescent multilayer disc, the fluorescent multilayer card was a memory device proposed by Consallation3D. It consisted of a card containing a square shaped clear part with multiple layers each containing a different fluorescent material capable of emitting light at a different wavelength from the other layers. By this approach, the device could contain several layers, each with individually addressable data. It was suggested that a card with the data area roughly 25 mm (one inch) wide could be able to hold 10 GB of data.
Famous quotes containing the word card:
“In the game of “Whist for two,” usually called “Correspondence,” the lady plays what card she likes: the gentleman simply follows suit. If she leads with “Queen of Diamonds,” however, he may, if he likes, offer the “Ace of Hearts”: and, if she plays “Queen of Hearts,” and he happens to have no Heart left, he usually plays “Knave of Clubs.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
