realistic shader for a vinyl record

[NNois]

Hi,
I'm running into a basic problem:
How to deviate a uv in a radial fashion ?
basically i would like to take a fractal shader and deviate his coordinates in circles.
In fact i understand well a good part of the MR nodes but when it comes to vector stuff i'm lost...
Anyone can guide me a little ?

Hi, I would just make a planar projection and use an image as texture (black white noise + radial blur).

thanks miga, it was my first thoughts but maybe i was dreaming but it could be done no ?
