Abstract

This invention provides for a hologram recording medium comprising a hologram recording material, such as a photopolymer or photopolymerizable material, sandwiched between substrates disposed in an opposing orientation, such as for the case of upper and lower substrates, wherein said the medium incorporates a material or materials for encapsulating the hologram recording material thereby preventing the exudation of components of the said recording material from the recording medium. The substrates of said hologram recording medium preferably are in a substantially coplanar geometry so that the outer surfaces of said substrates are substantially parallel, and at least one of the substrates is substantially transparent. The substrates of the hologram recording medium have peripheral edges separated in the direction perpendicular to the surface of the substrate by a distance associated with the thickness of the hologram recording material. The peripheral edges of the adjoined substrates are preferably aligned in a substantially planar arrangement but other suitable arrangements may be used. For instance, the peripheral edges of the substrates can be aligned in a non-planar or offset arrangement, or a combination thereof.
