A number of you know that often a DVD burnt today will be unreadable after a few years. It is not obvious to predict that the majority of what is burnt today will be readable in the far future, however this is not as unlikely as some think. The current situation according to the American public records is in the worst case, the lifespan of a DVD may be only two to five years. Of course, all this depends on the quality of the virgin disk, the quality of the burner and the conditions of storage of the disk.
The Cranberry company decided to fix this breach and offers disks that will remain intact for 1000 years. To arrive at this wonder, they have creates disks whose substrate of data storage is composed of diamond, supposed to be much more unalterable than any other substance.
Even though these disks can be read in any DVD reader, one needs a special burner to be able to modify this diamond surface. The burner sold with a batch of 150 discs costs the trifle of $4995. In order to offer their product to the greatest number, the company makes the offer to private individuals of buying 1 ($34,95) to 5 ($149,75) disks, where the user then sends the data to be burned on their servers and to receive in exchange by post, the burned DVD. If studies manage to prove that these DVD are really as robust as announced, they could represent an attractive solution to transmit family photos to one's descendants, all at least if someone manages to find a reader able to read these disks in a few tens of years. When one sees the speed to which the video tape recorders disappeared, this is not certain.
