Are Blu-ray discs durable?
Yes. BDs are coated with an extremely hard, protective layer called “Durabis ” or “AccuCORE “. Like CDs, the Blu-ray data layer is very near to the outer surface of the disc layer. Without the Durabis protective coating, BDs would be just as susceptible to damage as CDs. Durabis can take an incredible amount of punishment, even from harsh abrasives like steel wool.
