DIY CD Clarifier (pics)

[tubenut]

After having heard improvements in clarity after "treating" CDs with my old head demagnatiser (I no longer own a tape deck.) I decided to build a motorised solution inspired by the commercial CD clarifier.
A surplus CD motor, a self gripping spindle from a broken lap top CD drive, transformer, push down toggle and some caps and bridge wee glued and cable tied into a plastic box. The results are good!!!!

Here are some pics.

What the physical principle on which your CD clarifier works ?

Ooooooh, enjoy picking at scabs, do we?

Passive CD clarifier

These passive versions work just as well and are very cost effective. Physical principle should be self-explanatory. Clearly.

I won't comment on the physical principles or the scientific correctness but its nonetheless a nice piece of Diy.

For enquiring minds:

and

Information recording disc demagnetization apparatus

Hope this helps

I like the work on the aparatus, and I also find the patent interesting. However an aparatus doesn't require you to prove its effectiveness to apply for a patent (or am I wrong).
Has it been demonstrated scientifically that CD's become magnitised and that this has an effect on the "tone" ? Can anyone point me to a paper on the proven principle. I am genuinely interested, and hence my restraint in my original statement.

No scientific clue......
Heard the Bedini years ago and tried my old head demag thingy and heard the same kind of difference.
Just decided to make it more user friendly.....

The difference is varied depending on discs treated (play times maybe) but afeter reading the patent notes I am going to treat discs upside down (mag field will then be closer to label side) and hear what happens....

This audio game is just bizarre.....

You are not wrong. Not only that, but it doesn't have to actually work for a patent to be granted. There's patents on all kinds of outrageous nonsense.

I filed a patent on the inclined plane last year. It was rejected.

Hi,

I am sure that some of you will also need this Intelligent Chip CD upgrade with a valid scientific explanation of it's operation. .

Best regards,

So now we know why you have been so grumpy!

Since when is the reflective layer magnetic? I mean, any more so than I am.

I read the article on the chip thing. Not at all enlightening as to how a magnetic clarifier would work as they are using entirely different principles. Not entirely convinced by the scientific babble about the chip, I understand the principles he is describing - but in relation to a CD I think hes pulling our legs.

The real problem with verifying the worth of any of these devises is that audio memory is so short term. Simple taking the CD out of the CD player, having just listened to it, and "clarifying it", and then popping it back in - the chances of really remembering the difference is tiny, if it at all subtle. The user expectation of an improvement is likely to swamp any actual change.

I agree! Is that Michael Jackson in his latest transformation?

Don't say that at audioasylum.com. They will drag you out back, shoot you, and charge your family for the bullet.

At least two people don't like it. That's enough reason to keep it.

Hey, don't get personal, that's a picture of me. On a good day.
