It may look just like a typical Sony Discman, but Sanwa's CD-RE1AT doesn't play any CDs or DVDs. Instead, it helps to restore damaged discs and make them readable again. We doubt it would be much help for removing deep scratches or cracks, but this should prove useful for removing dust, fingerprints, and oily stains from the disc surface--detritus that can affect the performance of a disc.
But what also caught out attention is that besides cleaning, the Sanwa device apparently also applies a protective layer onto the disc to prevent reading errors in future without grinding it. The Sanwa CD-RE1AT retails for 7,350 yen ($69) on the Japanese market and is designed to work on discs ranging from 8 to 12 centimeters, including Blu-ray. It weighs about 300 grams and is powered by an AC adapter.
