When buying DVD rewriteable CDs, why do some have a plus sign and some have a minus sign.?

Answer 1

DVD-R, DVD-RW—The first standard, dating from1997
DVD+R, DVD+RW—Introduced by Hewlett-Packard in 2001—Get this one
DVD-RAM—An older, more limited standard
DVD-ROM—Plays DVDs; does not burn them. Do not buy this one.

R stands for recordable meaning these disks can be recorded/burned only once. RW stands for re-writable disks; they can be burned up to 1,000 times. RAM discs are also re-writable and supposedly can be burned up to 100,000 times (I seriously doubt this, but this is what the makers claim!).

Many manufacturers make their burners to handle both + and -. This costs a little more, but will give you more flexibility.

Are you planning to play DVDs through a television? If you buy a DVD burner that burns only one standard, check that your DVD player can handle that standard. Most newer players can handle anything, but older ones play either DVD-R or DVD+R, but not both. Check the DVD player’s instruction manual.

Answer 2

DVD's have 2 different formats. If you have a dvd burner, you need to find out if you have a DVD+ or a DVD-. Some DVD burners can burn both, if you have one of those, it does not matter.

Answer 3

They are both formats of DVD's. I myself prefer DVD +R because it has better error checking. I also prefer CD-R for the same reason! Good luck!

Answer 4

plus and minus are different formats. especially with older dvd players, certain players required certain kinds of discs. i believe sony was notorious for only reading -R and not +R. most newer dvd players will read both.

Answer 5

dvds that are r+ are newer and the sound and visuals
are way better than r-
