TDK's Durabis 2 coating protects 200GB Blu-ray discs
One of the consumer worries of Blu-ray Disc vs. HD DVD is the durability of that ultra-thin, 0.1-mm layer protecting your BD-stored data. HD DVDs on the other hand, use a comparatively thick 0.6-mm surface layer just like standard DVDs making them appear -- on paper anyway -- more rugged over the stretch, right? Not necessarily so. At least not when TDK or others apply protective coatings to their optical media. The 6-layer, single-sided 200GB BD disc on the right in the image above is coated with TDK's "Durabis 2" hard-coating technology -- the disk on the left is a standard DVD; both were subjected to equal treatment by the steel-wool and a Sharpie. Any questions? [Thanks, Dave]
