Axiom Home Page Forums General Discussion Technical Questions fixing a cracked CD

hey everyone,

I just realized that the inner plastic (before the actual part of the disc where the information is) has two or three small cracks. I'm afraid they will grow in size or destabilize the disc.

I don't want it to break (Peter Gabriel - Up - SACD, not cheap to replace and i cannot burn it), nor do I want it to explode in my player.

Does anyone know a good way to prevent these cracks from getting worst and make sure it doesn't eventually break the disc?

You could try plastic cement. It works by "melting" the immediate surfaces you apply it to and then bonding the surfaces together. It's supposed to form a bond as strong as the plastic itself. I would, of course, test this on a disk you don't care about, first.

You can find plastic cement at hobby and model stores. If you've ever put together plastic model cars/airplane/ships, you'll know what to look for.

Here's a page about it.

When you're ready to give it a crack -- no pun intended -- on your SACD, use a toothpick to apply the cement to both sides of the crack.

But then wouldn't you have to worry about putting too much cement that the weight of the disk is no longer centered?

Since the crack is near the center hole, the chances of unbalancing the disk with cement are small (i.e., the further out from the center you place extra mass, the more it will affect the disc's balance). Use it sparingly, and if there is concern of unbalancing the disk, apply the same amount to the opposite side of the hole.

very good idea. thanks. i wil try it on a blank cdr before the sacd.

i'll post here how it turns out

Wow... how did you crack disc media? I don't think I've ever seen radial cracks there...

Speaking of CD longevity - the first CD I ever bought will be turning 17 this year. Went into the ONE bin at A&M Records?!?... long defunct anyway... and picked up a copy of the Pogues If I Should Fall From Grace With God... remember carrying it home like it was the crown jewel... those high-tech compact discs and all!

I have no clue how it happened. I hope it wasn't like that when I bought it, because I can't return it (purchased in Hong Kong, I live in Montreal).

I take VERY good care of my cd's and therefore lend them to no one. This is the first time I see a crack. HOWEVER, when I bought The Downward Spiral on SACD, it was cracked out of the box! I got that replaced because I bought it here.

Perhaps I'll check my next SACD purchase a little closer

I have issues with some of the discs that come in the cardboard folders with the holder glued into the inside of the folder.
On two that I have bought, the part that you push in the center with your thumb is so tight, that when trying to lift the edge of the CD I have literally cracked the CD without ever getting it out of the holder!

the exact same thing happened to me with the NIN CD. I can't remember, but maybe that's what happened with the Peter Gabriel

Digipaks? Hmm... not one of my favorite ways of packaging materials. Luckily only got one in my CD collection (Sugar - Believe What You're Saying EP).
