...you're assuming that the aluminium in discs is 100% pure to begin with. I don't know if this is the case, but I doubt it.Aluminium itself actually is magnetically sensitive. It is said to be paramagnetic and will behave as a very weak magnet in the presence of a larger magnetic field. The effects are short-lived and it should quickly demagnetize itself once removed from the field, but the fact remains that it is sensitive.
I've tried using an old bulk tape eraser (I got a massive one for $10 on eBay) to "demagnetize" CDs. I noticed a difference that only lasted about 5-10 minutes. Something favourable definitely happened, but it was far too short-lived to be useful. I'm not interested in religious arguments, so I'm not going to speculate or label what’s happening here… but something definitely happened!
To get an almost identical effect, try this tin-foil trick and report you’re findings here if you want to start a war!
Listen to a CD you know well. Take a 12†square sheet of new ordinary kitchen tin foil and fold it once in the middle. Take the CD from the drive and place it in-between the leaves of the foil. Place the whole envelope in the palm of your hand with the crease facing towards you. Take your other palm and gently, but firmly wipe twice on the foil packet. Listen to your CD again.
I found a big increase in spatial information, but I might be suggestible. It'll take you 30-seconds to try it out and it's nominally free.
