RE: How about encasing the mechanism?

I had to jump through so I do not know if this has been covered - but whole ordeal indicates a lack of understand of how a CD works.

The pits in a stamped CD are � wavelength of light which causes a cancellation of the reflected beam. With a burned CD they are a layer of photographic type material in the layer which is darkened by the burning LASER.

A magnetic field does not affect either, this is physics, this is fact and indisputable.

For a magnetic field to affect the output of the LASER pickup it would have to be such a strong field that it would affect the LASERs ability to focus. The layer of whatever on the CD, burned or stamped simply does not have the mass to have such a field.

Facts of life folks, waste your money on something else. Otherwise, I got some DVD rewinders for sale.
