As the title says why does toothpaste fix disks
In: 2049
Putting toothpaste on a scratched disk is likely to only result in making it worse, and a tiny chance it’ll actually make anything better.
The “idea” is that the tooth paste will act as a very delicate abrasive in order to remove the scratches on the bottom of the disk. By effectively sanding down layers of the plastic, you can get down to a point to where the scratches no longer exist. This obviously only works if there are no super deep scratches that are almost the entire way through.
A lot of disks, as far as I understand, actually store the information on the very top surface of the disk. If you get “top scratches” on a gamecube disk, for example, the disk is basically ruined even if the bottom side is flawless.
If your going to get your disk fixed like this (the process is called resurfacing) then please use a proper resurfacing machine. They are expensive. If you don’t have one, your local video game store or music store will likely have one. They often will resurface disks for you for something like $1 each.
