US photographic company Delkin has developed a range of archival CDs and DVDs which claim to safely store images for up to 300 years. The secret ingredient? 24 karat gold.
Delkin eFilm Gold Disks feature gold in the reflective layer of the disk. The company says that because gold is one of the most inert and reflective elements on earth, it is able to resist the effects of temperature and humidity and thus prevent oxidation (a common cause of failure in CDs).
“By using an accelerated aging process to test the longevity of CD media, eFilm Gold CD-R disks have been shown to safely store images for 300 years, while the 4.7GB Archival Gold DVD-R media will safely store images for more than 100 years. This longevity is of special importance to archivists in museums, libraries and art galleries who need to preserve large amounts of irreplaceable material for the future.” the company said in a statement.
Cost: CD-R from $1.72 per disk, DVD from $3.50
