Donât conflate a mastered CD with an aluminum data layer with a recordable CD-R or CD-RW, which use organic dyes that have a significantly shorter lifespan.
A properly manufactured CD can last 200+ years if itâs stored in a dry environment free of UV exposure and high levels of moisture.
Even a quality CD-R canât really be expected to retain all of its data integrity for much more than 10 years.
First released in Japan in October 1982, the CD was the second optical disc technology to be invented (âWikipedia)
Sorta doubting whatever study found proof that a CD can last 200 yearsâŚ
Thatâs what I think when I read endurance/mtbf of hard/solid state drives of like 100+ years. Bitch you released this last week and I know for a fact that you didnât withhold sales for 100 years for validation of your claims. Also funny how I should reasonably expect 100 years out of it, but you will only provide a warranty for the first threeâŚ
Obviously no oneâs seen it happen first hand. Itâs a projection based on whatâs known about the materials and how theyâre made. Burned CD-Râs have definitely been out in the real world for people to learn how short their lifespans can be, though.
Nobody could âprove,â for instance, that the Voyager 1 could stay operational in deep space for 47+ years when it was launched in 1977, but the engineers could still predict and they launched it anyway, and it did. I donât think your argument really holds water.
