Abstract

The invention relates to a holographic data memory comprising a memory layer (2) in which a hologram (2a) can be inscribed by an energy supply, and a carrier (4) for the memory layer (2). Said memory layer (2) is arranged above the carrier (4). Said data memory is characterised in that it comprises an elastic and deformable compensation layer (5), and said compensation layer (5) is arranged under the memory layer (2).
