Beschreibung
Zusammenfassung:	A multilayer fluorescent information carrier (300) having a plurality of data layers (302), each of the data layers (302) comprises a thin controllable liquid crystal cell composed of two electrodes (303) and at least one orientation film (304 or 305) and information is recorded thereon in the form of orientation capability which is spatially modulated over its surface with respective to a liquid crystal composition and when playing back, it allows for partial or complete elimination of the fluorescent cross-talk from the adjacent data films.
