Submission + - Tough new optical disc coatings

An anonymous reader writes: As everyone who uses Netflix knows, scratches on DVD are frustrating and create significant customer support costs. Blu-ray is the first major disc format to address the problem. The chemistry [1] [2] [3] behind these coatings a radical-curing urethane(meth)acrylate and a curing monomer, and is applied unformly over the disc. The results are impressive — this video shows a Blu-ray disc surviving steel wool and a pizza cutter, which would have destroyed traditionally-coated formats (e.g., CDs, DVD, or HD-DVD). Fewer scratched discs also means less waste.
