demagnitizing CD s?

Here's another theory: the static charge in the plastic layer of the CD "bends" the LASER beam, causing jitter. Whatever the reason, my bulk tape eraser will continue to be used on every CD I play. All of which, incidently, have green edges.

albert: experimenting with tweaks is a fine form of entertainment among audiophiles. why should anyone waste his money, tho, on tweaks that don't work? i find it quite interesting to hear from those who have actually tried the demag devices their reports of results, or the lack thereof. if those reports are spurred by a clearly jocular post, what's the problem? i think most of us are adults here and can stand to have our "enthusiasm" questioned. what good would this forum be if it weren't for differences of opinion? i truly appreciate the increased level of civility in these threads of late and your efforts to establish and maintain that characteristic. i hope, however, that we can keep our collective sense of humor, lest these chats become akin to highschool historty texts screened through a sieve of political correctness into a tasteless pabulum.

Cornfedboy: As far as I'm concerned your first post says it all. At one time I owned the Ultra Bedeni Clarifier "product of the year". Yeah right...it made absolutley no sonic improvement what so ever, plus the build quality was cheesy to say the least.

Albert I think there are two types of Mag Lev trains in existence today (as far as I know) – one uses attractive magnetic forces and the other uses repulsive magnetic forces. Keep in mind that electricity and magnetism are forever linked together through Ampere's Law and Maxwell’s equations. Where there is current there is a magnetic field. Trains that use opposite magnetic fields are called electrodynamic trains. Trains that use attractive magnetic fields are called electromagnetic trains. So in the case of aluminum a current is passed through the aluminum and creates a magnetic field. A similar opposite current is passed through the rail and an opposing magnetic field is created. The two fields repel one another and the train is lifted. No back to the topic… If there is any charge on the CD (say like static) and you rotate that through a magnetic (say from internal power supply) field you have created current and a weak (I think opposing – not sure) magnetic field. If the laser pickup (wiring) is at all susceptible to induced EMI then I could see more "hash" in the system. Remember just rotating some wire through a strong magnetic field creates a generator I wonder if a CD behaves as a capacitor seeing how it is a conductor wrapped by a dielectric. It would be nice if the plastic were conductive so the platter could ground the CD as is plays - no charge - no voltage - no voltage no current – no current no magnetic field. Sorry for my EE rambling …. Cheers, Dan

Hey Guys, are we dealing with system deficiencies or hearing
deficiencies??? The difference in using the dual-beam Bedini
vs. no treatment is a no-brainer. The difference is not a
subtle thing at all. It doesn't have to be any particular
unit, but effectively getting the flux field off the CD has
got to be a priority for and type of serious listening.
