I'm a huge flaming noob

So I wanted to know the differences between DVD-R and DVD+R.

And whats the latest on the next gen of media...i heard some names like blue ray being thrown around.

good post, id like to hear what people have to say, i myself have gotten confused wiht all the misconceptions out there

The difference between DVD-R and DVD+R is who's backing what. DVD-R tends to read betters in settop DVD players.
Blue-Ray discs just means that they want to change it from red lasers to blue lasers, thus increasing the capacities of the discs.
HD-DVD seems to be popular for movies, as doubted by many sceptics. Blue-Ray seems to be heading towards console games.
Since Blue-Ray would mean re-doing their production lines, where-as for HD-DVD only a few minor changes need to be made.

wait, the only difference b/w blue ray and dvd is the f*ckin color/wavelength of the laser? and that would affect capacity, so why not start with the blue laser to begin with.

Dunno. I wasn't around when they invented CDs, my age was after that.

??? you werent around in the 90's? that make you like 10 years old??

That's not the purpose of the difference. Blu Ray and HD-DVD are two high definition dvd formats, as opposed to standard definition dvd. High def dvd will not only allow you to watch movies in high def, but also record shows in high def (providing you have an hdtv and hdtv service). Both formats have a blue laser instead of the red found in traditional dvd. They are both (Blu Ray and HD-DVD) brand new and as far as I know, no one has them for sale yet.

Actually CDs were invented in the early 80's, they were just put to market until the 90s.........I think it was in 1981-1982 they were made.........but i could be wrong........

DVD+R = Good. DVD-R = Bad. That's all you need to know. But if you're a geek and want to know more than you need to know, read up on the article about the DVD+R/-R format at cdfreaks.com

red laser pointers are ~$10 for a nice one. green ones are around $70 last time i checked, afaik they don't make blue laser pointers for consumers...probably too expensive. same with the lasers for cd drives

Cd's were introduced in 80 or 81 and disks were immediately available, although in very limited quantities.

The reason for the late adaptation of blue lasers is until recently it was not commercially viable to make them.

As for why blue gives a higher capacity than red its to do with wavelength, the shorter the wavelength the narrower and closer together the "tracks" on the disk can be. CD's used near infra red lasers, DVD players use red lasers and blu-ray, well blue lasers. In the future I'm sure we'll eventually see ultra violet lasers.

The one snag with moving towards shorter wavelength lasers is the amount of energy required to make the laser light, it goes up considerably for short wavelengths.
Hope this helps the red/blue question.

As for DVD standards I personally prefer using +R, seems to offer much better compatibility with DVD players.

 

[xsilver]

the only reason -R even has a stance right now is due to early ps2 compatability and because in certain places you can find them cheaper
so if you can, go +R

 

[Ike0069]

I have a Pansoinic DVD player that is about 2.5 yrs old and it won't recognize DVD+R. So I burn -R's if I want to play in on that DVD player, otherwise I use DVD+R.

 

[Zepper]

The DVD-R works better with the DVD players used with TVs - you have to change the booktype on DVD+Rs to get the same level of compatibility with the older players. Many of the stand-alone players are now rated to read both DVD +/-R so that isn't so much an issue but it always good to know and plan for the target of your burned disks.
