"we spin this medium at up to 500RPM for CD and a bit slower for vinyl.
33.33 RPM is quite a bit slower than 500 RPM. Good reason to be suspicious of the entire argument, IMO.

It's not the RPMs per sec it's the angular velocity. The angular velocity of the outer rim of the LP is relatively high and the surface area of the LP is considerably greater than a CD, about 4 times greater. And we don't known the minimum velocity required to produce the effect.But one has to wonder, ESP. In the case of the CD, even if it is degaussed prior to play, why doesn't the magnetic field reemerge after say 5000 revolutions?

The angular velocity is constant; the linear velocity varies linearly with radius at a fixed rotational speed.
Thanks for the correction.
personally i am not as interested in figuring out why it works as i am in IF it works. if the process works as its proponents claim, then its probably worth doing. imho.
