[QUOTE=GadgetVictim;84258]@kelson,
Thanks for pointing this fact out. I'm learning something new about BD-R and DVD discs every day, which helps me make more informed purchase decisions.:)
I Googled "LTH media" and found this enlightening info in Wikipedia:
"... BD-R LTH is a write-once Blu-ray disc format that features an organic dye recording layer. The advantage of BD-R LTH is it can protect a manufacturer's investment in DVD-R/CD-R manufacturing equipment. .... Old Blu-ray players and recorders cannot utilize BD-R LTH, however, a firmware upgrade could enable the device to access BD-R LTH..."
After doing some further googling, it looks like there's two camps in this area of blu-ray discs: Low to High (LTH) and High to Low (HTL).
SOME LINGERING QUESTIONS STILL REMAIN UNRESOLVED:
1. I assume the older BD-R were all HTL, and the reason for switching over to the newer LTH is that it's less expensive to produce?
2. I'm assuming also, that when people refer to "non-LTH" or "standard BD-R", they're referring to BD-R HTL discs?
3. Since this particular forum addresses "BD-R life expectancy", the question now is, aside from initial incompatibility issues, which of the two technology would have a longer data retention/storage life span? Seems like this depends a lot on who the disc manufacturer (i.e., TY, Verbatim, OQ, etc) is the ingrediants/standards/qualities they apply.
4. Finally, when I purchase BD-R from places like Amazon, can I assume that all the BD-R not specified as being LTH are infact, HTL discs? Example:
a. Not all the BD-R offered are not clearly labeled as being either LTH or HTL. Examples:
- http://www.amazon.com/Optical-Quantum-Double-Inkjet-Printable/dp/B002LZMY10/ref=sr_1_1?ie=UTF8&qid=1304542987&sr=8-1)
- http://www.amazon.com/Verbatim-97339-DataLifePlus-Single-Layer-Recordable/dp/B004477BQQ/ref=sr_1_1?ie=UTF8&s=electronics&qid=1304545933&sr=1-1
b. However, there a some that are clearly marked as being LTH. Like the Verbatim brands: http://www.amazon.com/Verbatim-97090-Blu-ray-Single-Layer-Recordable/dp/B002WCRC2S/ref=sr_1_1?s=electronics&ie=UTF8&qid=1304543172&sr=1-1
However, note the difference in per disc price between the two Verbatims above: #97339 vs #97090.

LTH is pressed on the same press they make DVD's thats why the cost is cheaper, these disc's were first developed back in 2007. I know verbatim makes them but not sure of who else. I think most disc's that you come into contact with will be normal BDR. It comes down to basically you get what you pay for! If you buy the expensive disc's e.g. Verbatim, TDK you are most likely not going to encounter any error if you go with the cheap BD R's its a crap shoot! I use TDK and I don't burn coasters nor do I get any errors!
