When the CD was introduced back in 1983 the manudacturers claimed that they were indestructable! Far from it, many CD's are now actually rotting away and not playable, why? There are many reasons and some of them include, bad quality of glue, bad manufacturing practices initially, bad quality of ink, careless storage, temperature variations etc etc. The list can go on and on.
I have a CD full of pinholes, going back to 1984, although I bought it when I first purchased the cd player in 1987, The cd is on Philips label. I use it even today as a test cd since many players seem to have a problem playing this one, I guess it is a good test of the error correction system. All my current players are able to negotiate this disk without any problems. My experience has been in the past that some of the cheaper players had difficulty playing this disc. I used this CD a lot when some of my friends wanted to buy players, besides the music, I used this disc to test out new players.
I remember having read an article long time ago probably in early 90's stating that the ink developed for printing initially would penetrate the polocarbonate layer and eat up the aluminium foil layer so Dupont did research into ink technology and came up with a new type of ink which would take care of the problem. Apparently after 92 or 93 this problem was solved. This does not happen with all the early cd's since I have a few still in my collection from the mid 80's and they are fine.
There is an interesting article in USA Today which should be an eye opener for most of us. Take a look at what the author thinks could be the reason and how we can protect our treasures.
CD's and DVD's - not so immortal after all
