I've had read failures on older CDs so I'm not so sure about trusting that media. Then again I've had hard drive failures, too. One in particular nuked a whole bunch of my wife's images...Ooops sorry honey.
About the only media that I think we could consider truly archival would be thumbdrives/solidstate hard drives and/or prints. Even though the digital photography technology is getting better it's still far too easy to lose information as it is to copy it. Printers are getting better and the inks have better longevity but the age of a print done in the darkroom is still so dependent on getting the chemistry right. My parents have a 25th. anniversary poster sized print of my sisters and me on their wall at home. It's now over 30 years old and fading! I don't believe we have the neg on that one either so when the print finally ghosts away that will be it for that particular memory.
Oh well, the image only has importance for the family and is worthless otherwise.
Speaking of 'worthless' I read or heard somewhere that a 20cent piece of plastic suddenly becomes PRICELESS once something is burned to it.
However, your idea of 'immediately burn a CD' would have made my wife a WHOLE lot happier when the hard drive FAT went...gooblegook! I did manage to salvage a handful of images but the rest...well they just weren't recoverable at all. Oh well, chalk that up to experience.
So...if one was to burn these images to a CD or DVD are those higher priced discs truly worth the expense? Are they 'safe'?
