In an ideal world, we would be able to repair a disc to such a degree that the finish is identical to when it the disc came off the assembly line.

But this just isn’t possible because of the softness of the material. It also isn’t necessary in most cases for the finish to be that good. The main purpose of disc repair is to get the disc to simply play again.

The quality of finish you can expect from all the good disc repair machines out there, is fairly similar – it is just a question of how much time, money and effort is required to get the finish.

Is a perfect finish always necessary?

The answer is no.

b2ap3_thumbnail_scratch-depth-image-550_20130628-155857_1Most machines repair to a ‘like-new’ condition – this means that to the un-trained eye in normal lighting, you won’t notice any difference from it and a new disc.

But under stronger light and with closer inspection, you will notice tiny hairline processing marks, left behind from whatever abrasive or heat based method that was used.

Because most machines remove the surface of the disc at an incremental rate, then it is only a matter of time before the optimum finish is reached. But the point at which the disc becomes playable again, is usually well before this.

If you are selling second hand games or films cheaply, then consumers don’t expect the disc finish to be absolutely perfect. They just expect the disc to play. However if you are selling fairly recent titles at a higher price, then the customer will expect the finish to be much better.

You can then tailor how long and with what process you repair each disc, cutting costs and time.
