Blu-ray Disc thickness and durability?

[Anthony P]

the thickness of CD, DVD, BD nd HD DVD is the same

CD has the information on one side of the disk (just under the label), DVD and HD DVD in the middle, BD at the other side (actually at a .1mm depth)

BDs have a scratch resistance coating added on to it during manufacturing (part of the .1mm over the data). It makes them much tougher to scratches then DVD.

awesome. thanks. then my question is this: why are so many people reporting problems with their blu-ray discs they're renting from blockbuster? maybe its a concentrated amount and whats being reported is overblown because only negative comments come to the surface and therefore become the center of attention. i've just been hearing a lot about that lately and thought it was less likely to scratch a blu-ray than the other competing formats?

It seems to me the the BD is more sensitive than a dvd when it comes to fingerprints or debri. I clean every rental disc with eyeglass cleaner & eyeglass wipes. I really haven't got one with significant scratches yet, mostly just dirty discs or a couple with small cracks on the very outer edge. (1 played, 1 didn't)

So many people aren't reporting problems with Blu-ray rentals from Netflix. If you ask the HD DVD supporters at AVS, they will say their is a bunch of problems, but of course, they don't rent Blu-ray discs, so how would they know? The coating works.

well, the reason behind the hard coating was that the blu-ray laser is much more precise and fine tuned to read the data off the tippy top of the disc than hd dvd or dvd. so the slightest scratch and the disc is done. so to ensure that the discs would work and be durable the coating was added, however fingerprints, dust, anything that could hinder that laser reading the disc is going to screw it up. as long as the disc itself hasn't been hurt just wipe it off with something soft and put it in and it should be fine. ive yet to not be able to solve a playback problem with this.
