    摘要: Optical media of a limited usable life are disclosed. The invention relates to chemical formulations and methods and processes for creating time limiting mechanisms for the inclusion in optical media thereby providing optical media with a limited usable life in which encoded information may be accessed, played and/or read for a prescribed limited time. The invention provides formulations and methods for corrosion of and/or the corrosive degradation of a reflective layer(s) and/or reflective material of optical media such that the encoded information stored on an optical medium can not longer be read by a reading beam.
