There is disclosed a method for the holographic recording of data, wherein a hologram containing the date is recorded in a waveguide layer ( ). The holograms are formed in a layer structure containing multiple waveguide layers ( ). Coupling means ( ) are provided for selectively coupling the reference beam ( ) into the single waveguide layers ( ) of the layer structure. The invention also relates to an arrangement for holographic recording of data, comprising a data storage medium with a waveguide holographic storage layer, and an optical system for writing and reading the holograms. The optical system comprises means for imaging an object beam ( ) and a reference beam ( ) on the storage medium. The arrangement comprises multiple waveguide holographic storage layers ( ) in the storage medium, and means for selectively coupling the reference beam ( ) into the single waveguide layers ( ) of the layer structure.
