Blu-ray more scratch-resistant than DVD
Blu-ray discs are more resistant to damage caused by scratches and fingerprints than DVDs due to a TDK hard coat applied to the surface of the disc, according to proponents of the storage format.

Hi, I look after product development for CBS Interactive in Sydney - which lets me develop a range of websites including CNET Australia, TV.com and ZDNet Australia.
Blu-ray discs are more resistant to damage caused by scratches and fingerprints than DVDs due to a TDK hard coat applied to the surface of the disc, according to proponents of the storage format.
Michael Hoog from the Blu-ray Disc Association and Michelle Garra from the Blu-ray Disc Working Group discuss disc durability with CNET.com.au at the official launch of Blu-ray in Australia:
- What is the lifespan of a Blu-ray Disc?
- Can Blu-ray really survive being scrubbed with steel wool?
- Does having more data on Blu-ray compared to DVD increase the amount of damage a scratch causes?
- What effect will online delivery of content have on physical media such as Blu-ray?
