>The mechanism used to focus the laser assembly is electro-magnetic.<
More specifically, it is usually very similar to the voice-coil of a loudspeaker driver.
Many disc clamping mechanisms also utilize magnetic operation.

Re: Demagnatizing CDs?
But the question is, how does that material come to be magnetized to begin with that it would subsequently need to be demagnetized?

The soldiers were silent, and looked at Alice, as the question was evidently meant for her.
`Yes!' shouted Alice.

There are probably trace amounts of ferric materials in the dust on the disc as well as the stuff in the disc label (on MY discs, not your's- I know you keep YOUR discs cleaner than I keep mine). I suppose from a philosophical point of view, as long as one magnetic molecule remains on the disc, it COULD have some effect on the sound. And by that logic, a disc demagnetizer COULD have some effect on the sound as well.
There, you've beaten me into submission - I've admitted that a disk demagnetizer could have some effect. Now I think I'll go try out the rumor I've heard about self-trepanation improving the sound of my system. Anyone care to join me?

Don't any of your CDs have printing on them? Pictures, name of the CD, band, ect. I have some opjective measurtment experiments in mind for the objectivist.
"I've heard about self-trepanation improving the sound of my system." You need not poke a hole in your head to be open minded you know.

It is sometimes hard to keep an open mind...
/UrSv
A boat, beneath a sunny sky,
Lingering onward dreamily
In an evening of July -
Children three that nestle near,
Eager eye and willing ear,
Pleased a simple tale to hear -
Long has paled that sunny sky:
Echoes fade and memories die:
Autumn frosts have slain July.
She still haunts me, phantomwise,
Alice moving under skies
Never seen by waking eyes.
Children yet, the tale to hear,
Eager eye and willing ear,
Lovingly shall nestle near.
In Wonderland they lie,
Dreaming as the days go by,
Dreaming as the summers die:
Ever drifting down the stream -
Lingering in the golden gleam -
Life, what is it but a dream?

Come to think of it, I did an experiment some time ago, painting
a CDR black on the top side and outer rim using black acrylic
paint. It didn't work. The CD player refused to play beyond
some 40 seconds. I never investigated the matter, but now it
is suddenly all clear to me. I used Mars black, which is an iron
oxide pigment. Guess I have to demagnetize it. 😉 😉

Floppy Sonics
There was a suggestion a while back about cracking open a 3.5" floppy and placing the floppy disc ontop the cd disc before loading into the player.
I tried this with a 5 1/4" floppy (I trimmed 10 mm from the diameter) and it did change the sound subtley.
First impressions were that I did not particularly like the change and I have not got back to trying it again.

What about freezing disks? I never tried it but people report good results. Might try it today. Why not?😉
When I demagnetize my tools they become "unmagnetic" (for my needs) but maybe this isn't enough for your friend?
Yes the watchmakers screwdriver needs to be totally non-magnetised, or else it can grab and damage tiny hair springs in the watch mechanism.
I posted this info so that members here may try demagnetising components - Bernard ?.

Mpingo Magic....
Can not comment on the Mpingo Disk, never try it.
Anybody here have experience and impressions of the Mpingo discs ?
