View Full Version : Scratch ...

14th Mar 2002, 03:44
... I should f*****g kick myself!!! Just damaged my favourite Red Hot Chili Peppers CD! <img border="0" title="" alt="[Mad]" src="mad.gif" /> . .. .I heard a while ago that it is possible to "repair" CDs. Anybody know about it? Is it worth the money, or do I have to make EMI happy and buy the same album again? <img border="0" title="" alt="[Roll Eyes]" src="rolleyes.gif" /> . .. .One more reason to justify a CD burner for myself ... <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />

why not just buy the album again, and use the damaged copy as a rather "trendy" drinks coaster?

Simple! Because I am NOT a fancy BA or Virgin pilot... <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <img border="0" title="" alt="[Frown]" src="frown.gif" /> . .. .Wonder if you would get hired by them admitting that you dare to listen to this kinda funky music.... <img border="0" title="" alt="[Eek!]" src="eek.gif" />

Squawk, I had a scratch damaged game cd repaired and repolished recently. . .. .It came back just like new and at about a fifth of the replacement cost. Being cheaper, music cd's might be harder to justify.. .. .The people who did mine were at pains to point out that single cd's were the most expensive, and the cost dropped significantly with multiple units.. .. .Find your nearest repair agent and ask them the cost, enquiries cost nothing.

It is possible to polish them out yourself.. .. .The best polish is Jewellers rouge and has been used for polishing scratches out of glass for a long time. If that is not available I have used "Silvo" which is a liquid finely abrasive silver polish sold in OZ but any quality liquid metal polish is worth a try. It takes a considerable effort and you should use small circular motions in the area of the scratch.. .. .Another thing to try is play the disk on your computer. The spin speed being what it is can often overcome some scratches which throw a CD player. If it works then burn a new one from that.. .. .I know the Silvo works as I often have to "fix" my sons Play Station games as he just leaves them all over the place.. .. .Good luck

In the past I've mended cds with T-Cut (don't know if other countries call it that, but it's stuff for restoring the paint on a car to its original glory).. .. .It takes off the top layer of coating of anything, so if the scratch isn't too deep it might be worth trying.

I seem to remember hearing that tooth-paste can be used to polish out the scratch...?. .. .Haven't tried it myself though.

All the above should work but I would reccomend you try them out on a CD you don't value first. Basically you are looking for the finest abrasive possible that is consistent with getting rid of it without having to polish forever.

Good point Gunner, but it is a "Red Hot Chili Peppers" album, so bring on the steel wool! <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />

Silvo eh? I've been using Brasso for years. <img border="0" title="" alt="[Wink]" src="wink.gif" /> . .. .As to how, the direction IS important. The tracks on a CD are sprial, there is only one track actually. Scratches ALONG the track cause read errors, whereas scratches across the track are far less likely to be a problem. So when you polish the CD, use a radial motion, straight in and out (where have I heard that before?) rather than any motion which moves along the direction of the track.. .. .Good luck.

I saw a 'cd repair kit' in Virgin megastore last week. It costs about 20 quid and repairs scratched CDs in a few seconds (I dunno how though!)

15th Mar 2002, 23:30
Just a bit of trivia to add to Feeton's most excellent advice.... .. .The spiral track is 0.5 microns wide, with an inter-track gap of about 1.5 microns (a micron is one millionth of a metre). So you can see how a scratch going with the track can cause you severe problems!. .. .Incidentally, if laid out, the spiral track is .5 microns wide and about 5km (3.5 miles) long. <img border="0" title="" alt="[Wink]" src="wink.gif" /> . .. .DVDs take this to a whole new level - apart from there being multiple tracks, EACH track is way finer than good old CDs... Tracks are 320 NANOmetres wide and would stretch 7.5 miles ... Oooh! <img border="0" title="" alt="[Eek!]" src="eek.gif" />. . . . <small>[ 15 March 2002, 20:49: Message edited by: sanjosebaz ]</small>

Didnt realise the tolerances were so fine. I scratched my CD trying to play it on my gramophone and I think i should have used a softer needle. I tried to take the scratch out with an angle grinder but that just made it worse. maybe I should have stuck to 180 wet and dry?

Thanks guys! Eric, I got some steel wool every time I come across a Spice Girls CD ... <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />

Skytrucker, are you sure you were using the right grinding disk with your angle grinder?

Forget CDs. They are expensive and old news. Go to . .. .www.audiogalaxy.com. .. .You can download any (and I mean any!) song you could ever want. Only really worth it if you've got cheap and fairly fast internet connection. If you do though, a computer can become your very own personalised juke-box of delight. If you've got a CD burner, then HMV will never see you again. <img border="0" title="" alt="[Smile]" src="smile.gif" />

Pretzel Logic . .. .I checked the Audiogalaxy site out - it does seem that anything and everything is there. I used to use Napster until it was closed. <img border="0" title="" alt="[Frown]" src="frown.gif" /> . .. .Recently I've used Morpheus from Musiccity although the variety is not there yet.. .. .How long has this site run? What experience has everyone else who uses it had?. .. .Rich

Silvo or Brasso work as described.. .Then wash the CD with luke-warm water & detergent.. .Then wash it with alcohol/meths.. .Then spray lightly with Mr Min or some other silicone. .wax based furniture spray and polish nicely.. .Works for all but the worst - repeat if needed.

Well, you're right... They've got Everything:. .. .David Allan Coe - "you never even called me by my name". .. .Found it straight away <img border="0" title="" alt="[Smile]" src="smile.gif" /> . .. .But.... "You cannot request this song due to copyright restrictions. Please try a different search.". .. .Aaaarghghghghghhh !!!. .. .What's the farkin' point if they don't let you listen to the bleeding song once you've found it ?????. .. .Ah well, there's always "Cum stains on the pillow" ..... . . . <small>[ 17 March 2002, 20:46: Message edited by: Grainger ]</small>

Grainger,. .. .Your songs can be got at, but they may be called something unusual. In order to bypass the site’s copyright obligations the songs are only banned from download if they are given their official name. People call their song files odd things to get around this. For example, ‘All Right Now’ by Free may be called ‘All Rite Now’. (Either that or the general populous cannot spell for toffee). This does screw up the search function sometimes but try as lose a search as possible. . .. .If this fails then type the name of the band only. This should produce a list of all tracks by that band, and you are free to search them. Problems can still persist but it is all the fun of the fair to try and beat them. I have never failed to get a song. . .. .When I first found the Holy Grail of internet music, for the first two or three days it really was bliss. Every song that I had ever wanted from the age of six was there. However, be weary of the man who is suddenly given everything he wanted. After a short time you run out of songs to get, but deep down know there are thousands more. You begin to search through friends’ record collections and read strange magazines just for inspiration. Before long the experience has left you shallow and empty. You want for nothing, and feel bitter at the theft of all the challenge in your musical ambition. . .. .Therefore it is a slight mercy that audiogalaxy is such a tight b$%tard, or else you’ll find yourself a humourless and unrelenting cretin like me. <img border="0" title="" alt="[Frown]" src="frown.gif" />
