what is the difference between the + / - on dvd/cd/br discs?

[Infamous]

i got the R and the RW, but i dont get the + or -

Back in the day recording DVDs wasn't a unified deal, some used the minus R, some used the plus R. I'd say just about all DVD burners today can do minus and plus. But back in the dark ages, Win 95 and under I'd say, there were minus R burners, and plus R burners. They didn't do both. How ever, after the disc was burnt, it could be read by either.

Not true Devilguns. I worked at Circuit City for many a year and most CD/DVD players you'd plug in to your TV would play one or the other, but not both.

Typically your computer DVD drives will read and write to both, although sometimes you'd only be able to write to one. If you want a good read on the differences, here you go:
