ABSTRACT:
FIELD OF THE INVENTION
The present invention pertains to the field of information storage mechanisms, and more particularly to the elimination of access to information contained on information storage mechanisms and method of fabrication.
BACKGROUND OF THE INVENTION
Information storage mechanisms currently found in today's market include many durable media formats. The most common of these durable medias are compact discs (CDs), digital video discs (DVDs), and magnetic tapes. Durable medias are commonly found in many industries including the movie and music industry, and are often utilized in the dissemination of consumer information. At a basic level, the information contained on existing durable media often lasts an inappropriately long time given the content, sensitivity, or application of the contained information. Forecasts, census data, safety procedures, and the like, all have lifetimes after which the data can no longer be relied upon as current. Unfortunately, the durable media on which it is distributed lasts beyond this useful life allowing careless individuals the opportunity to misuse the outdated information.
In the video rental industry, movies are typically contained on durable media which last beyond the rental period, thus the media must be returned to the store. This is both inconvenient for the consumer and the vendor in keeping track with the media. In the instance of sensitive material that is contained on a durable media, the information must be tracked extensively and explicitly destroyed at a costly price, in that the data will last for an extended period of time.
One of the most common of the durable medias, CD-Rs (recordable compact discs), employs dyes and variants which exhibit widely different tolerances to light exposure in determining the media lifetime. Specifically, cyanine dyes are most commonly used in CD-Rs which are considered to be relatively stable and therefore provide for recordation of data for an extended period of time. In many instances, such as those described above, this extended period of time in which the recordation of information is contained on the durable media presents a problem.
Thus, there is a need for a media in which access to information contained is eliminated or the information actually expires upon the happening of a preset determined occurrence and upon predetermined expiration variables.
Accordingly, it is highly desirable to provide for a new and improved media format in which information contained thereon is deemed perishable in nature upon the happening of a preset determined occurrence.
It is a further purpose of the present invention to provide for a new and improved perishable media format in which access to information contained on the perishable media is eliminated based on predetermined factors.
It is yet a further purpose of the present invention to provide for a new and improved perishable media in which recorded information is destroyed based on a predetermined use factor.
It is still a further purpose of the present invention to provide for a new and improved perishable media in which recorded information is destroyed based on a predetermined time factor.
It is a purpose of the present invention to provide for a new and improved method for fabricating a perishable media in which a material which provides for the elimination of access to information contained thereon the perishable media is provided in addition to standard media fabrication materials and techniques.
SUMMARY OF THE INVENTION
The above problems and others are substantially solved and the above purposes and others are realized in a perishable information storage mechanism, including a substrate, a data layer for recording data thereon the communicative media, including a material responsive to at least one predetermined data elimination factor, a reflective layer, and a protective lacquer coating. In addition, included is a method for fabricating a perishable information storage mechanism including the steps of providing a substrate, forming a data layer on a surface of the substrate, forming a reflective layer on an uppermost surface of the data layer, and forming a protective coating in an uppermost surface of the reflective layer.
