300 year warranty for CD and DVD media

Branded as Kodak, a CD/DVD media manufacturer, KPM, will propose media with an extended warranty: 300 years for CD and between 80 and 100 years for DVD.
To support their claims, they have used high quality gold (24 carats) supposedly to improve the lifespan of products and especially damage generated by daylight. Of course such media are more expensive and will probably be used by corporations wanting to improve the reliability of stored data.
It is also an obvious marketing claim, and one would have to ensure that, in 80 years from now, drives able to read such media will still exist ... rather unlikely.
