There are basically two machines that repair DVD's:
1) Buffing machine, such as the JFJ Easy Pro. For scratches, it includes sanding pads that actually scrape off a thin layer of polycarbonate, then buffs it back to a high shine using two successively finer polishing compounds.
2) Heat machine, such as the Venmill units. They aren't cheap, but they don't remove any of the polycarbonate. Instead, they heat it up and press it, like an iron, which softens the polycarbonate and literally presses the scratches out.
The problem with BD-ROM's is that they are not made of the same materials as DVD's. They use a thinner back, and a new harder scratch resistant material for the data side. But, it is not immune to scratching. You can't use the heat machine on it, because it is heat resistant. And you can't sand it, because it's too hard. You won't be able to buff it back to a useable state.
The best you can try is just the polishing compounds either by hand or on the JFJ machine. If it doesn't work, you're SOL.
I think BD-ROM manufacturers should switch to using the same polycarbonate as DVD's, like HD-DVD, which could be repaired using either of the above two methods.
Venmill has stated that they are currently developing a Blu-Ray repair machine, but won't give any details on anything about it yet.
Has anyone used any other methods successfully on a scratched or scuffed disc that has unreadable sectors on it?
