Abstract:
A method of separating a substrate and a thin-film material of an optical recording memory media using ultrasonic comprising the steps of:(a) placing an optical recording memory media in an ultrasonic environment; (b) using ultrasonic to damage weaker interconnected interfaces of the optical recording memory media; and (c) enabling the interconnected interfaces to absorb energies for attenuating and losing adhesive forces thereof with other layers, wherein the ultrasonic environment is a soak bath containing a liquid and capable of producing ultrasonic oscillations, wherein the soak bath works in coordination with increases in temperature, addition of organic solvents, application of vacuum cleaning and running water, and agitating using mechanical forces for shortening a time period required for separation, wherein the organic solvents are combinations having appropriate ratios from any of solvents having strong cleaning strengths and high flash points as well as being dissolvable in water, emollient solvents softening strengths between layers, buffer adjuvants reducing corrosion that the aforesaid emollient solvents have on substrates, additive accelerants promoting speed of damage of the aforesaid emollient solvents with respect to layered structures and additive antistatic adjuvants preventing peeled off adhesive objects from re-adhering to the substrate.
