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:
“Mothers are not the nameless, faceless stereotypes who appear once a year on a greeting card with their virtues set to prose, but women who have been dealt a hand for life and play each card one at a time the best way they know how. No mother is all good or all bad, all laughing or all serious, all loving or all angry. Ambivalence rushes through their veins.”
—Erma Bombeck (20th century)
