How to eliminate magnetic distortion in optical media

Surfing in the web today, I found another "sweetie" :p This is dedicated to audiophiles, that always search for perfection in their audio equipment:

The silk-screened label on an optical disc contains chemical compounds such as iron, nickel, and cobalt. These materials are strongly magnetic and easily remagnetized. The reflective information-bearing surface of optical media contains 99% aluminum, but 1% of these same highly magnetic materials! Even aluminum is considered a weak magnetic conductor.

...

Demagnetizing both sides of optical media before play results in a greater sense of power, dynamics, and resolution, with cleaner, blacker backgrounds and a larger, more stable soundstage, vivid tonal colors and deeper extension at both ends of the frequency range. Demagnetization also communicates the delicacy, refinement and nuance of a performance, along with the micro- and macro-dynamics needed to realize the full potential of music and movies.
Using the deMag improves the sense of surround sound involvement in every two-channel and multichannel home theater system. Visceral, exciting sound heightens the emotional and participatory sense of music and especially home theater.

Well, I must confess that this leaves me speechless. I always thought that CDs and DVDs were simply optical media, and that in optical media the only important thing is that pits and lands are not damaged in some way.

If this tool is really able to remove any trace of dust from discs, this is really a good thing, because dust can make more difficult for a laser to read informations stored in the disc. Many of people here at CDFreaks knows how a single grain of dust can make a quality test scan really ugly.

And also all people (like me) that still plays LPs surely know how disturbing dust can be on LPs, so a tool able to remove it from these is very welcome.

What seems a bit strange for me, however, is that on optical media all information is stored in digital form, and what is on the disc will remain as it is even if the disc is magnetized, so apart from removing dust I really can't understand the usefullness of this tool.

Oh, wait a minute... What is this? Oh... I just noticed that the price is "only" $ 1,800. Hehe... now this makes sense, doesn't it?
