摘要:
Methods and apparatus are provided for making an optically readable storage media in which the reading beam passes through a bonding layer configured with a reactive material that transforms from an optically transparent state to an optically opaque state after exposure to a predefined stimulus, thereby inhibiting access to the data encoded on the optically readable storage media. The method includes steps of synthesizing a blocked dye combining the blocked dye with a carrier material curing the resultant combination deblocking the dye to produce a reduced dye in the resultant bonding layer exposing the optically readable storage media with the reactive material in its bonding layer to a predetermined stimulus. In a further aspect of the present invention methods and apparatus are provided for making an optically readable storage media wherein the reading light passes through the bonding layer and the data encoded information is encoded on the L1 substrate. In yet another aspect of the present invention methods and apparatus are provided for making an optically readable storage media with at least two mechanisms for limiting access to the encoded data of the optically readable storage media.
摘要:
Systems and methods are described for inhibiting the readability of an optical media due to changes in a pseudo-reflective material that composes the optical media after the optical media has been exposed to air for a predetermined time. An optical media includes a data encoded component. At least a fraction of the data encoded component transforms from a substantially optically reflective state to a substantially optically non-reflective state as at-least-in-part a function of time from an initializing event. The systems and methods provide advantages because of low cost, limited content lifetime, avoidance of rental returns and minimum changes to existing manufacturing processes.

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.
摘要:
A data storage device comprises a first substrate and a second substrate, wherein at least the first substrate has defined thereon a plurality of pits and lands covered by a reflective material; and a bonding layer between the first and second substrates including a reactive agent that interferes with the passage of light in response to predetermined stimulus. In another embodiment, an optically-readable storage media, comprises a substrate having encoded data stored thereon, a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range, and a second reactive agent that, in response to predetermined stimulus, degrades the readability of the encoded data.
