Abstract
A method for making an otical recording medium comprises providing a substrate which is encoded with information in the form of pits and/or a continuous groove beforehand at least on one side thereof, spraying a solution or dispersion of a film-forming material containing at least one organic compound having optical functionality in the form of a mist onto the encoded side of the substrate in a vacuum chamber under conditions sufficient to permit a thin film to be formed thereon in a substantially solvent-free condition, and drying the thin film. An optical recording medium obtained by the method is also described.
