Archival CDs and DVDs
There have been past discussions about the archival quality of CDs and DVDs. The summary as I last remember it is that the ultimate archival quality CDs are like the ones from Delkin and the DVDs were not nearly as trustworthy. However, we're finding in digital photography, we're shooting heaps of stuff and the CD capacity limit is real small. Of course there are other media and backup methods, but I was intrigued to see Kodak archival DVD-R at the local Safeway. Not cheap at AUD 11 per piece in a hard plastic case. I then re-visit Delkin and they are claiming Blu-Ray discs (BD-R) at 200 year lifespan, CD-R and DVD-R at 300 year lifespan. Amazing how some accelerated testing and extrapolation curves can produce eh? Now, if only we could find a computer, in 300 years that reads current CD-R. And the relevant RAW and JPEG editors.
