scratched CDs..

I know this has been done before, but cant remember what was said.

Was it BRASSO that people said removes scratches from CDs?

Also, is a CD like an LP; i.e. are the first tracks on the edge of the CD and the last tracks in the middle?

Im just trying to work out where the offending scratches are!

Cheers

Mr Sheen + cigerette ash

 

Other way round - CD is read from inner to outer, so the first tracks are in the middle, last tracks on the edge.

 

And DO NOT wipe around - but from centre out in straight lines

A CD runs from about 500 rpm to 200 rpm to keep the speed of the linear velocity constant. I'm guessing that scratches nearer the outside of a (fully recorded - ie 80 mins) CD would be worse than in the centre due to disc wobble, but I could be wrong.

Certainly scratches that cause a disc to stick have a shorter repeat (e.g. dddddddddddddddd) near the middle, and sound more like "dur dur dur dur dur" nearer the outside

 

Brasso or silvo (finer) light abrasives can be used to work through the scratch in the polycarbonate - but it is quite difficult and shouldnt be attempted on a valuable cd. Also if the top surface in damaged and light can be seen through it then there is no repair that i know of, in fact im sure this is irrepairable. I have heard that t-cut will also do a good job.

 

Jewelers rouge is by far the best thing I've tried for this. Can be obtained on line here. http://www.englishcustompolishing.com/eneu/jewellers.html

 

owwww a tenner?


What was second best thing youve tried mate? n


Ive only got the one flocked CD..

mr sheen and cigarette ash .. a joke, surely?

 

Thats what i thought when WM suggested it, but it does work

 

hmm, not sure that taking up smoking is a good way to try and revive one cd!

 

I was told at a CD cleaning demo in Singapore that scratches on the shiny side of a CD have no effect at all - unless they are huge gouges - and that if there is a problem with a CD, it is due to a scratch on the label side of the disc .... and this cannot be repaired.
I'm no technician so others will know better than me.
I do use toothpaste to clean (rather than remove scratches) on the pirate DVD's we buy here in Vietnam. I run from the center to the outside and this seems to salvage a lot of the dodgy DVD's we get here.

 

Skip Doctor

I've got a device called a skip doctor, as I'm too lazy to use Brasso as it requires loads of patience.

It works a treat, but obviously some damage is irrepairable.

Got mine in a virgin megastore, a search in google should be able to source one.

Hmmm... I'm not sure toothpaste is the best idea for just cleaning, since it is mildly abrasive (as Tones taught us all recently ). If it does what you want then go for it, but personally I'd look for something else.
