Abstract

The present invention relates to a microwave apparatus to accelerate CD recycling by pre-damaging, and particularly to an apparatus for placing the optical recording medium under an electromagnetic wave environment so that energy of electromagnetic wave is concentrated to damage the film layer of the optical medium, including the protection layer in the optical recording medium, since this layer may hinder the subsequent recycling chemical reaction, so as to significantly increase the effective reacting interface of the chemical solution, and assist the chemical solution to further separate the film material from the substrate material along the cracks. The whole method is easy in operation, low in cost, and fast and reliable in dissolution, which is helpful in high-quality recycling the substrate and film material of the optical recording medium, and which can effectively avoid the secondary contamination in the recycling process.
