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.

Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a micro-device for accelerating the recovery of an optical disc by using pre-destruction, and particularly refers to a method for placing an optical recording medium in an electromagnetic wave environment: The concentrated energy of electromagnetic waves destroys the thin film layer of the optical recording medium, including the protective layer in the optical recording medium. This layer will hinder the subsequent recovery of the chemical wind reaction. In this way, the effective reaction of the subsequent chemical solution can be greatly increased to help the chemical solution along the crack. A device that further separates the substrate from the substrate material and the thin film material. [Prior art] Optical recording media are roughly classified into optical discs, write-once discs, and re-write discs by their physical classification. One of the ROM CDs is a known CD, which is sequentially plated with a reflective layer and a protective layer on the substrate layer:-of the sub-type optical disc-is a known CD-R, which is based on the substrate layer and the layer, the reflective layer and The protective layer is formed; moreover, the rewrite is a known CD-RW system consisting of a dielectric layer, a dielectric layer, a reflective layer, and a protective layer sequentially on the substrate layer.
