EP1155406A1, EP1155414A1, US6522616, WO2000048197A1; A multilayer optical information storage medium, such as a card, uses a luminescent, fluorescent, or electroluminescent material to reproduce information in the form of incoherent radiation. Each layer has multiple pages of information. A specific page on a specific layer is addressed by moving the card relative to a read head so that the image of the specific page to be read is focused on the read head. This can be accomplished by moving the card in the X, Y, and Z directions, or by holding the card stationary and by moving a two-dimensional image detector in the X, Y, and Z directions
