Ongoing History Daily: Tape and CD rot

It goes without saying that we as a species would like to preserve our music forever and ever, right?  But here’s the question: what format will last the longest?

It’s certainly not magnetic tape.  Archivists in the UK have found a strange and powerful mold that’s creeping from tape to tape like a virus, eating and destroying everything as it goes.

And it’s certainly not CDs and DVDs.  There’s something called “laser rot” which is a form of corrosion.  It happens once the aluminum reflective surface squished between those layers of plastic becomes oxidized.  You know your disc has gone bad when that reflective surface turns brown.  Once that happens, you’re done.

So what’s the best physical storage medium for music?  For the moment, it’s still vinyl.
