| It didn't break but looks like an attempt to peel the recording surface?

| Was it unburned? Either way a financial hit or a data hit  |

| So much for Blu-ray's ultra-tough coating if it turns out that this coating is fixed with a weak adhesive.  As the laser lens in a Blu-ray drive hovers very close to the disc surface, I would strongly advice against loading this disc, as the laser will almost certainly strike the split part of the disc, potentially leaving you out of pocket on an expensive Blu-ray drive also. As Rolling suggested, it would be worth bringing it back to see if you can get it exchanged, as dropping a disc should not cause this. |

| This does not bode well for the long term reliability of BD discs. I drop DVD's all the time and never see any damage except scratches. It looks like the BD disc is constructed much like a CDR, (only in reverse), which is definitely NOT good. HD-DVD discs are constructed just like a DVD. So here it seems is some evidence that HD-DVD is superior in one respect. |

| Well I was curious so I dropped a 0.5oz/15gr BD-R disc from a 2nd floor (15ft/5m). It didn't break, glue still bonds but lots of nicks, compare to the first post --smooth edges....

Your disc does not look like the same brand from OP's pic. Maybe you have better discs? |

| This is a whole new dimension to media testing that I never even thought of before reading this thread!

There isn't anything inherently wrong with the 0.1 mm protective layer, except when the adhesive doesn't get properly cured - in which case you can pretty much peel it off. I've seen Ritek DVD DL discs where the two 0.6 mm substrates split from simple bending, so (HD-)DVDs are not immune from bad curing of adhesive either.

| I can't say I'm INCREDIBLY surprised by this, I've heard nothing but terrible things about TDK's BD-R media from within the recordable media industry itself. Of course competeting brands are a little biased, but I've still yet to hear any POSITIVE news about TDK brand BD-Rs from anyone "in the know" on the manufacturing end. That being said, I've heard of DVD-Rs seperating when they've been dropped on the ground, from several different sources now.

For HD DVD-Rs, I haven't seen any tests with current drives and media that have been within spec yet (C't latest tests show a '--' score for Verbatim media even! )

It's a new BD-R technology using organic dye. You can read about it here at CDRLabs.
