A two stage moulding procedure for the production of foil video discs. In a first pressing operation a satin finish consisting of a surface irregularity is applied to a surface of the foil, and then, in a second pressing operation, the foil is pressed between stamper plates to impart thereto, at one or both surfaces an impression of the information or data to be recorded. The satin finish may be formed by pressing the foil between stamper plates bearing the satin finish at their inwardly facing surfaces or alternatively between a pair of rollers bearing the satin finish at their surfaces.
