Hi all,

Feel free to disagree out there, but there has been longstanding agreement amongst digital preservation practitioners that there is NO long term archival storage media, nor will there likely ever be. We have entered an era where content (or data) and carriers have much different lifespans and are managed entirely differently. Storage media should be viewed as temporary. In the digital age, we are not in the business of preserving media, rather, it is the content that is the target of preservation. Ensuring that optical discs will be playable in 5, 10, or 20 years due to obsolescence, data rot, mishandling, and myriad other factors is not something that archives will want to be dealing with moving forward. They are highly unstable and their dependent technologies are quickly disappearing (the computer I am typing on does not have an optical driveÖ). Furthermore, it is very logistically challenging and time consuming to migrate data off of these formats, or to do any automation with these (unless you have a big disc library). Formats such as spinning disk and data tape, for their short lifespans, offer much more resiliency, store more data, and are much more accessible today, and easier to migrate off of. Which you are going to have to do, period.

The CBS story (and similar story on NPR on August 18) is primarily about dealing with legacy optical media. There are a lot of these things from the 90s and 2000s that archives and libraries have in their collections, and they will have to find a way to preserve the contents held on these discs. What these stories donít raise is that storing new content on any kind of optical media is highly unadvisable. 

This is just my $0.02, but I assume that the NSDA is fairly unified on this topic. Perhaps Iím wrong. In any case, I would not recommend gold DVDs or any optical discs for that matter, for the long or short term.

Thanks,
Kara
