Abstract
The DVD-D is a standard DVD that can be used only for several hours after the card board sleeve has been opened. But the sleeve can be opened anytime: now, in one day, in one week, in one month or in several years. Then the DVD-D has a restricted lifespan of eight hours, after which it will be more readable by some platforms. The technology is compatible with any type of DVD drive (DVD video players, DVD-ROM drives, DVD game devices). It does not require any hardware change. The automatic erasure of the DVD-D is made possible thanks to a technical process consisting in deteriorating the layer of aluminium, presents on the surface of the disc, by a substance non-toxic released at the time of the opening of the nut fixed on the DVD-D.
