Follow up to this.
It’s just a scam. Everything in the marketing copy is a lie. Nothing about it will do anything to the sound produced by the disc. Yet there are still articles at the top of Goole search results, talking about how much better CD’s and DVD’s are heard and seen after using this… device.
Let’s break this down.
The layer of metal that CD’s use to reflect the laser light is aluminum oxide.
We could stop right here, because the entire idea of “demagnetizing” a CD is a farce, since, as everyone understands, aluminum isn’t magnetic. But let’s set that aside for a moment, and continue. There’s an even-more ridiculous reason this whole idea is patently stupid.
A molecule of aluminum oxide, consisting of Al2O3, would be approximately 478.5 picometers across.
CD lasers run at 780 nanometers.
Even if the molecules of aluminum were somehow “inverted” from their original, stamped orientation, due to “magnetism” induced by the label printing process, first, it could have no effect on the signal produced because there’s no part of the laser decoding that depends on molecular orientation, and second, any material in the disc substrate that has been “flipped” would be invisible to the CD laser, as the molecules themselves are 1,500 times smaller than the laser can distinguish.
But, yeah, someone made this, and people have bought it, and I’m certain that they “heard things they’d never heard before” in their music. Further, I’ll bet it’s still being offered for sale in “audiophile” magazines.
