This is a most excellent place for technology news and articles.
You do know its much safer and much more highly available to store it in a cloud rather than a piece of plastic, right? In a cloud you get it raided on multiple sites, etc… obv. Depends on how much you pay. Dont forget that CDs in their best of best conditions had a lifetime of merely 10 years. Dont know how much this new media holds with such density…
And you do own the data, read the contracts.
I'm not saying you don't own the data, I'm saying it's more expensive than storing it yourself. Obviously it depends on the purpose and budget; if you need it to be highly available and secure, and you have thousands of dollars to direct to the project, the cloud is great. If you want to make a backup of all your DVDs that fits on a single disc, it might be overkill.
The sort of data suited to discs like this is probably pretty different than the sort of data suited to an S3 bucket. It could make a decent tertiary backup though, a local copy of your data stored on offline media can be a lifesaver.
This isn't a competing technology to the cloud, it's complimentary.
