Why demagnitize an optical reader?


I've read numerous times now that folks state to demagnetize a CD or optical disc before playing it for best fidelity and accuracy.  I don't see how an optical device, which is non magnetic and made from non magnetic materials benefits from a demag process.   Does anyone have any information to support this?  Other than hype, of course.

It has also been asserted that the inks used the non-read side of a digital disc have magnetic properties that can have a negative effect on the sound of a played disc.
