METHOD FOR INCLUDING GRAPHIC OR SIMILAR PATTERNS ON THE RECORDED FACE OF AN OPTICAL INFORMATION CARRIER AND OPTICAL MEDIUM USING THE SAME

摘要

The invention relates to a method for writing graphic patterns on the so-called useful face (20) bearing information (2000, 2001) of an optical medium (2) comprising the production of said support (200) made of transparent material, the selective deposition of a first material (203) with reflective property on the useful face over an area in correlation with the graphic patterns, the uniform deposition of a second material (201) with reflective property and the deposition of a layer of protective varnish (202). The first (203) and second (201) materials have different colors to distinguish, by contrast effect, areas covered by the first layer of uncovered adjacent areas, when the useful face (20) is illuminated by a source of The invention also relates to optical media (2), CDs or DVDs produced by the method.
