To understand how a scratch remover can fix a disk, you need to understand how optical disks work. On the data layer, a optical disk is basically a mirror. When the laser fires over the disk, the system will run over dark spots that are placed on it. When the laser reflects back it interprets it as a 1, when it doesn't it gets a 0. Your computer takes all of this and compiles it into data it can understand. This reflective is layer is very thin and quite vulnerable. To protect it, the disk is then sandwiched in between layers of plastic. It's usually just the plastic layer that is damaged. When the laser encounters a scratch on the disk it can reflect back at an odd angle, rendering the disk unreadable.

Scratch removers basically buff the surface of the disk to try and alleviate that. If you read the box most of them will say that they can only fix light scratches.The reason for that is is that if the scratch is deep enough, it can get to the data layer. Once that has been damaged there is no way to recover it.
