ABSTRACT:
A method of manufacturing an optical memory disc, which includes the steps of forming a volume holographic image on a recording medium by interference between an object beam (OB) of coherent light after passage through a mask and a reference beam (RB1) of coherent light, which is totally internally reflected at a surface on which the recording medium is disposed. Thereafter, the mask is replaced by the optical memory disc and formed on a photoresist or other photo-sensitive coating thereof is an image of the holographic recording using a second reference beam (RB2) replayed in the opposite direction from the first reference beam (RB1).
