MULTI-LAYER OPTICAL INFORMATION CARRIERS WITH FLUORESCENCE READING/RECORDING AND METHOD FOR THEIR PRODUCTION

摘要

A method of manufacturing a multi-layer optical information carrier with fluorescence reading/recording is presented. A structure (12) is fabricated, being formed of a substrate carrying a fluorescent film on one or both surfaces thereof, wherein the substrate is transparent with respect to incident radiation used for the fluorescence reading/recording. A patterned structure is applied to the fluorescent film under predetermined process conditions, such as to produce a fluorescent patterned structure with a surface relief in the form of an array of discrete fluorescent regions. The same procedure is repeated a required number of times, so as to obtain at the end of the process a multi-layer optical information carrier.
