Abstract
A method for separating optical recording memory media substrate and its thin film material. It is to place the optical recording memory media under the electromagnetic wave environment, by the nature of electromagnetic wave characteristic to focus large amount of energy onto the optical recording memory media thin film layer, to break the bonding between the substrate and the thin film layer and effect an thorough separation between the substrate and the thin film layer. It is a simple method with easy operation, low cost, quick and thorough separation. It makes possible the high quality recovery of the substrate and thin film layer; it also eliminates any secondary pollution in the process.
