Demagnetizing CDs...do they work? (1 Viewer)

[Ron Reda]

I'm not sure if this belongs in the "Tweaks" section, so here goes...

I was curious to hear of anyone's experience with demagnetizing CDs. Did you hear a difference after running the disc through your player? How often do you need to demagnetize? What specific demag CDs can you recommend? I've read plenty about them in Music Direct and Audio Advisor's catalogs, but am not sure if they're "snake oil" or what. I mean, to me, they seem to have some merit.

Thanks!

My opinion is that they are snake oil.

I agree, CD is an optical medium, how could magnetism affect it?

Anything that claims to demagnetize a CD is most likely bunk and I'd stay away from it.
However, some of the "tweaks" out there that de-static a CD are for real and do work.
Static build up is a problem with CDs and does affect the tracking ability of the servo/laser. Some of the anti-static tweaks work.
But I'd stay away from anything claiming to demagnetize aluminium.

Unlike iron, aluminum is not normally magnetic, so there's nothing to demagnetize.
