Ed it would help to put even some remotely resonable numbers on this. How many Teslas and spin rate. The answer (I'm sure) is ridiculous.
How about swapping the connections to the fuse holder (soldered of course), but leaving the fuse in as-is Ed?

Now for a real question and answer I am sure one of you can answer for me. What I have observed is that the worst thing and only problem I have ever encountered with a cd is when it has some extremely bad scratches and can't play or just totally mis-tracks. I imagine that this causes either diffraction or refraction of the laser light source, but why can some cd players seem to play some disks like this while others can't do it at all? What differences are causing this ability for the laser to be capable or not of overcoming this situation?

BTW Saw a nice concours for brass bands on the TV. Many European bands battling for first price. The jury sat at the back of the hall - behind a large curtain! Said the jury president: we only want to judge the sound, not the presentation, the costumes or the reputation.

You crack me up!
Drugs are drugs, homeopathic or otherwise. Best to stay away when possible, could end up causing yourself more problems than you started with.
Not 100% sure but I believe it has to do with things like capture range and loop locking in the servos. Its really a non-linear control system with a feedback loop with the same issues as any feedback loop.
Another issue may have to do with the digital side of the error correction, which depends on storage register size and thus on costs.
Am I close?

Ridiculous, no. But just getting near such a magnet would probably wipe your credit cards. I can't do an accurate calculation without knowing more about the metal film. Just for ease using magnetic lines of force as the unit makes such calculations easy.
The other issue is rotational velocity. Get it fast enough for long enough an the CD will shatter.
The point was a mechanism could exist. But that is not what is claimed.

All part of my article on power supplies. The AC mains to the circuit breaker box all the way from the power plant has a maximum resistance of .06 ohms to comply with code requirements. So much of the power line loss is in the branch circuit, outlet, power cord and connectors, switch and fuse.
I suspect turning the fuse holder around also could be measured, but it is easier to just try different fuses. That shows a reasonable amount of variance. The lesson is to use brand name fuses that are rate for about 80% of the current when you short the power transformer secondary.
Again I am of the OPINION that if you measure at extremes you can always find something.

There is the joke about the man in the garment industry who is successful and sends his son to school to get the education he never had. The son emerges from four years of business administration and the father turns over the business to him to run.
Months later father visits. It's clear that things are not prospering. All sorts of evidence that they are losing money. So the father questions the son about his procedures. After talking about schedules and ledgers etc. the son says And then I set the price at 10% over all of the fixed and variable costs per item.
The father goes Ah HAA! That's the problem! That's WAAAY too much markup! Two percent is plenty! It costs you a dollar, you charge two dollars!!
I know a woman, quite intelligent, who didn't know what 2% meant (thought it meant to double something, as in the practice for retailers to charge twice what they pay for an item, also known as keystoning).

How is it that distortion of the 60Hz AC power line matters at all, after it's been rectified and filtered?
Ed Simon,
Now if you could perfect that spinning magnet that would not wipe out my card but would wipe out my bills that would be a novel invention and I bet you would have lots of customers!
I do appreciate your thorough answers to these esoteric questions about things like fuses though. I did think about the heating of the metalized film on a cd but it seemed more than far fetched that any normal audiophile tweak would ever get close to that much power!

Ed, thanks! Fuse size? What happens when you take the fuse out and replace it same way round? What's the order of magnitude of these distortions compared to the amp distortion? Any sense of the R&R?
edit: I see Jan anticipated this as well.
edit: I think an order of magnitude calculation of the heating is pretty easy, since that's your latest hypothesis. You can assume about 5 ohms per square conductivity of the aluminum. I can get heat capacity and conductivity (i.e., diffusivity) numbers for the polycarbonate, if you like. You can plug in a WAG for the magnet strenghth- credit cards are not relevant here, their strips comprise MAGNETIC particles.
