Beware those magnetized LPs...

I have one but it violates rule 8.


I would love to know why vinyl needs to be demagnetized...

They explain all that...

The fact is that pigment added to the plastic during the manufacturing process is the culprit. The minute amount of ferrous material in the pigment causes LPs to become magnetized.

Mmmkay?

They are citing testing "at the Tokyo Nanotechnology center".

There is such a place, I just looked it up. I wonder if they would be willing to verify the claims?

Gee, I wonder if it works on cassettes and VHS tapes as well?

Well, it definitely works on hard drives. :D

I have one comment. The first paragraph says this device completely demagnetises (emp. theirs) LPs. But later on, they show that the measurements they took only change by 8%. So... which is it, guys?

Darn. Beat me to it. :)

Apart from a measly 8% reduction, they haven't shown that the sound from an LP is, in fact, changed at all, with everything else being equal. It seems to me that a field strength of about 6 milligauss is insignificant compared to the EM coupling between stylus/cartridge and playing surface resulting from static charge differences.

Not only that, if you tie it to a string and wave it around your head, it keeps tigers out of your neighborhood for 24 hours.

If you dip it in your fishtank, it cures your fish of laryngitis.

It also makes an excellent coaster for your 7/11 Big Gulp.

I like how treated vs. untreated plots (Figures 1 through 4) look exactly the same.

" Particular attention is due MD as it’s the most prone to magnetization effects such as problems reading discs."

Wow - that's amazing who'd have thought that a magnetic media would be the most prone to magnetization effects!

Isn't MD Mini-Disc, which is optical?

[Darat]

It's a digitial "magneto-optical medium".

Old Iron Butterfly albums are particularly at risk to becoming magnetized and need to be treated daily.

On a more serious note, placing a Magnetic Fields CD on this device will invoke a positive feedback loop that could emit a potentially lethal dose of bad vibes.
