What does +/-RW mean on a dvd drive?

[Erik]

I found a samsung drive that looks pretty good but it says DVD+/-RW. I don't know what that means, + or -?? Can someone explain this to me?

+ and - are different formats, it just means it can write both.
Also, and no offense intended here, but how did you get to 2[H]4U without knowing this?

Thanks.


And the way I got here without knowing this is twofold: I posted 90% of my messages about 3-4 years ago, then dropped out of the PC world for a while. Also, I usually post in the games, displays, and photography/art sections.
