DIY CD Clarifier (pics)

tubenut · 22nd May 2005, 02:19 PM

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 ?

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:
Apparatus and method for reducing electronic relaxation noise present information recording medium

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.....
