The durability of a DVD disc is determined on how long the information on the DVD is readable. That is if there will be a compatible device that can read the information on the DVD and how long the disc will last until the data is no longer readable. There are five things to take into consideration when looking at the durability of the DVD disc, the quality of the manufacturer, quality of the organic dye, sealing method, a good reflective layer and how the disc was stored. In order to be able to read the DVD disc in years to come it is important to know how long the manufacturer is guaranteeing its longevity. Some DVD’s are only good for 10 years and some go out as far as 100 years.
There is also a difference in the type of disc you are storing. Many manufactures have a true archival disc that is protected by a gold layer that they state will last 100 years. The other issue a DVD disc can have is if the bottom layer of the disc gets scratched. They can withstand light scratches, but if a deep scratch goes across the bottom of your disc where the data is written, there is a good chance it is now ruined or unreadable. I always recommend too make a backup of any DVD that is important and store it in a safe place. If there is ever a problem with your playable copy you can have your backup DVD master duplicated again. There are many companies that offer DVD duplication and you should be able to find one in your area by searching on the Internet. Phoenix DVD Duplication, for example, will find many duplicators near Phoenix.
