DVD-R vs DVD+R

[Murlyn]

Ok what is the difference between DVD+R and DVD-R? Hopefully the answer to that will help me figure out which I need to get

Thanks!

if burning on the mac, get +r, -r isnt read by all dvd players, +r is read by 99% of all dvd players, so its safer, and I use it and it always works great.

That is a good question. I was wondering about that my self. I believe the older DVD players can only read the DVD-Rs. That is the one I use to be on the safe side.

Most, if not all, current model Apple machines by default use a pioneer drive based off the DVD Forum DVD-R preferred standard. Unfortunately DVD-R don't support multi-layer burning, where as DVD+R media does. I think the DVD Forum is pushing to make DVD-R the standard for the obvious piracy reasons (hollywood can buy >4.7GB DVDs, consumers cannot. without multiple layers, it makes it harder for consumers to make a copy without knowledge of compression or the proper tools).

Besides the notebooks, all Apple machines support many other optical drives with an IDE interface. I personally upgraded to the Pioneer A07-U (8x +/-)

while DVD-R have the same potential for larger capacities, they were setup using a much denser film (which makes sense, they came out first and we've come a long way in LASER technology and its applications with thermodynamics). a denser film would make it harder for a LASER to have consistent reflection of light.

however, they are coming closer to having dual-layer DVD-R:

i think this kinda defeats the purpose of having a standard, since DVD-Rs work in the majority of DVD players(about 96% and DVD+R is about 87% according to CDRinfo test results), and this new dual-layer technology can't guarantee the same compatibility

As if anyone needed yet another high-capacity optical disc format to contend with, a company called New Medium Enterprises has been showing of their new 20GB high-definition Versatile MultiLayer Disc, saying that they’ll have drives and up to 30GB VMDs ready by Fall of next year. It’s hard to see VMD catching on given the complete lack of support from any major manufacturers or any movie studios (which the Blu-ray and HD-DVD camps are each trying to convince to release high-def movies in their disc format), but the fact that VMD uses a red laser rather than a blue laser does it mean it’d be easier for factories pumping out DVDs and DVD players to switch over. They just probably won’t.

i personally think this will be a huge contender for next generation optical storage if they can get support from a large vendor. using red LASER technology will save many people from the dreaded compatibility issues that come with newer technologies. even though they claim blue LASER discs will be compatible with many DVD players, there isnt enough testing until mass amounts of people try it.

Wow thanks you guys.. in other words it sounds like it doesnt really matter which I get at this point

an update on dual layer DVD-Rs .. apparently, theyre now available
