I can't think of any affordable form of media that won't decay over time. Even the old yellowing photos printed on photo paper are decaying while stored in shoeboxes across the world. I just took a bunch of old photos out of the musty decaying photo albums and scanned them into digital format and I was shocked as to the amount of decay they have gone through in only 30-40 years. Who knows how long data will remain on magnetic media?
