A method for forming a protective barrier layer between the active dye layer and the disc substrate during production of an optical memory disc is provided wherein a pre-treatment/pre-coat solution is applied to the disc substrate. This pre-treatment/pre-coat solution includes a surface modifier having an index of refraction approximately equal to that of the disc substrate. Surface modifiers utilized in this pre-treatment/pre-coat solution include poly vinyl alcohol, poly alpha methyl styrene, cellulose acetate, poly vinyl butyral and nitrocellulose.
