In Reply to: The Death of the CD... posted by AAG on July 1, 2014 at 15:34:14:
The Library of Congress determined that the only media that would survive as a true archival medium (lifespan measured in decades or centuries rather than years) were the LP and the stampers that made them.
All other forms of recording (analog and digital tape, CD, magnetic disk) would fail due to failure of the non-amorphous medium separating from the carrier layer (in magnetic tape this is known as 'shedding'), due to absorption of water molecules.
They determined at that time that the LP would survive in proper storage for 1 to 2 centuries due to its amorphous non-laminated nature. I have LPs in my collection that have lasted 60 years so far (monophonic Bernie Goodman) and still play fine. Only 40 years to go...
