How long will CD-R's & DVD-R's last?
There are archival quality CD-R's and DVD-R's. These discs from Mitsui have a life expectancy claim of 100 years because of the 24K gold reflective surface. Even if they are wrong by 50%, 50 years should be enough for most things. Regards, Rich |
They do deteriorate. It also applies to regular CDs as well as the recordable CDs. It is my understanding that deterioration is primarily due to poor quality construction of the CD itself. Some will last longer than others depending upon how well it was made and what materials were used. If you search the archives, you'll find some previous threads on this topic. |
I have read in one report that claims DVD+/-R will only last as short as 2~3 years. when I told my friends and we are all engineers and one of them used to work for a lazer diode company that read/write DVD, no one believed me. but it got me worried and I did archive more often now since media is so cheap. |
