Do disks crack more easily than DVD?

7270 Views 50 Replies 35 Participants Last post by  JohnES1
So far I have rented three BR disks from Netflix, the first arrived in perfect shape. The second two arrived with a tiny crack at the edge of the disks. I've been renting from netflix for years and the only two cracked disks I have gotten were cracked right in half from some idiot at the postal service placing weight on them.

Same here, got a BR from Blockbuster (Little Man) today with a crack on the outside edge (about 1/4" long). In the 3+ years I've been renting DVDs (first with Netflix, now also BB), not once have I received a broken disk. Probably just coincidence.
Well this doesn't sound good. Does the crack show through both sides of the disc, or just the data side?


One of my biggest pet peeves about DVD & HD DVD is that the two halves of the disc are clearly physically separated in the center. This makes them prone to cracking when in cases with poor hubs.


(The 0.6mm halves seem much weaker than the 1.2mm whole glued together. I never had such problems with regular audio CDs.)


I thought BD would solve this, but if they actually use a 0.1mm layer of polycarbonate to cover the data... that's potentially prone to cracking - that would be a major down-side for me.
I rented X3 from NetFlix, and it too had a small crack at the edge of the disc (unfortunately large enough to prevent it from playing)... I hope we're not seeing an issue here!
Over the years I've received at least 5 cracked DVDs from netflix, I'd say it's just the way they are handled in the mail.

Considering that you only came across 5 cracked DVDs over the years when thousands are being rented, I would consider this a cause for concern when there are only a tiny fraction of Blu-Ray discs being netflixed by comparison, yet someone already came across two cracked Blu-Ray discs. If it's the way they're being handled then either the handlers are extra tough on Blu-Ray rentals, or perhaps there is a yet-to-be-seen inherent issue with Blu-Ray discs and they are more susceptible to these cracks. On the other hand, it could very well just be coincidence.
I had one cracked BD disc. Same as the others, cracked on the edge. The disc played through though, although I did not try the extended features. I may have just gotten lucky.


I have only had one other cracked disc, that was a DVD and was completely cracked.


I wonder if the hard coating they apply makes the discs more brittle. It certainly does help against scratches, as the HD-DVDs I've rented seem to be more scratched on average. So far, I have yet to rent an HD format disc that plays with even a slight hiccup (BD or HD-DVD).
I only rent BD discs from blockbuster online and I received one with a crack as well. It played through with no problems so I did not think anything of it until I read this thread.
It's a small rental pool, perhaps you all got the same discs.


Hey, it could happen.
I too just got 4 blu-ray disks from NetFlix and ONE was cracked on the edge all the way though about 1/4" in from the edge (Superman).


I like Bluray but was curious if these are more fragile.
"Cracks" in this thread have been repaired. Any further damage to the thread and I'll have to throw the whole thing out.

Maybe someone should post photos of these cracks so that others know what to look for.

You would think they would be less fragile since BD uses one substrate (piece) of plastic like CDs where as DVD and HD-DVD uses two pieces which are glued together.

One would think, but it may be possible that a harder coating results in a more rigid disc, which consequently produces one that is also more susceptible to these cracks. As anyone who has had a cracked windshield will tell you, cracks can spread over time. If Warner is using the same coating (haven't read on this yet) on their Total HD hybrids we might see a problem with those as well down the road.
I've gotten 3 disks from BB online so far, 1 was cracked, crack extended toward the center from outside edge about 1 inch.
i cant comment on bluray disks, but i did get a hd dvd from blockbuster that skipped like crazy. they disk was full of hairline scrathes.
Wow, that's quite a few cracks for such an early format. HD DVD on the other hand scratches easily.

I agree, cracks should not be happening to Blu-ray discs already when they have a special hard coating to help protect and resist scratches. Fortunately for HD DVD, the data is 0.6 mm under the disc's surface, unlike Blu-ray which is only 0.1 mm.
I have never gotten a cracked dvd from netflix/bb in years of renting. I just switched to BR... I got 2 rentals that were pristine, then when the third title came it had a cm long crack in the outer edge and would not play in my PC so I requested another. The replacement (same title) came and it had a 3cm crack in the outer edge so I requested another. I just got the (third) disc today and it is fine...
