What is the difference between DVD-R and DVD+R other than the dash and plus?

The only physical difference between the formats is the way they determine the location of the laser beam on the disc. DVD-RW/R discs use tiny marks along the grooves in the discs, called land prepits, to determine the laser position. DVD+RW/R discs do not have land prepits, but instead measure the "wobble frequency" as the laser moves toward the outside of the disc

DVD-R and DVD+R are to different types of single DVD write formats. The DVD-R is most compatible with set top DVD players. All modern DVD burners support both types of format. The DVD-RW and DVD+RW are formats that can be written to and erased up to 1000 times.

If your dvd burner is listed as "DVD +/- RW" then you can use either DVD-R or DVD+R discs. I'd recommend using DVD+R discs, generally speaking, the blanks are cheaper and can burn faster.

you can't do this to a dvd-r disk. What you can do is buy a brand new for a couple of bucks. This is the society of spending, so re-using something is actually not good for the system. Are you a communist?? ;-)

Not all DVD players support dvd+r. Statistically is is a slightly more incompatible format.

It's just two different formats of DVD media.  If you plan to use either make sure you're DVD writer is compatible with the type you plan to use.  Most of the newer drives can let you use both types. They will say something like DVD±R (DVD +/- R).\nCheck out the two links below.

CD-r burns on the bottom of the disk, where a CD+R burns on the top.  There is really no difference in terms of use.

-r & +r are 2 different standards (read, ways) of burning DVDs in a dvd writer.\n\n-r/+r burns read only discs that can only be written to once, as opposed to +/-RW which allows you to wipe the discs and start again.\n\nRead the attached article at wikipedia for more info!\n\nHope this helps..

There's a software called DVD Copy Plus.

If you know that you are going to make a dvd recording and won't mess up on it then use the dvd-r because you can only use that disk once. The dvd-rw is a good disk because you can record over it if you decide you don't like what you recorded on that disk. just remember that -r is for recording once, and -rw is for recording over whats on it.

Is it a dvd that you burned yourself? You can only change a dvd-rw or a dvd+rw because the dvd-r and dvd+r are read only and cannot be changed to read and write. Hope this helps. Rock.

DVD-ROM is a dvd drive, DVD-RAM is a type of DVD http://en.wikipedia.org/wiki/DVD-RAM\nthat can be burned too.  DVD+/-RW is more common.  If you just bought the computer and it is a new computer, you have a DVD-rom drive or a DVD+RW or -RW drive.  DVD-RAM isn't really that common anymore.  Easiest way to check what you I have I have found is to either go check your system components in the control panel, look at your invoice or open up your burning software, odds are if it gives you the option to burn a DVD you have a DVD RW drive and you should just see if it is a + or - RW drive cause their are different blank DVD's to use for each

CD's dont have the plus and minus conventions, only DVDs do.  This is because, there are two competing groups that manufacture DVDs, the "plus" forum headed by HP, Dell, etc. that manufacture DVD+RW, DVD+R, etc. and the DVD Forum headed by Pioneer which manufacture DVD-RW, DVD-R, etc.\n\nHence, CD-R and CD-RW are valide conventions, CD+R and CD+RW are not.

The + and - of the DVD R are two competing formats, +R being developed by the DVD+RW Alliance, and -R being devloped by DVD forum. Both allow recording of up two 4.7GB on a single layer, and 8.5GB on a dual layer.  The primary difference is some drives do not read one type of the DVD, and so dual drives are popular, since they can read both formats. Dual burners are also popular.\n\nAs far as I know, there is no difference in burnable CDs, A CDR is a CDR, there’s one format. Different types of CDs react differently in different drives (older drives sometimes have trouble reading certain media), but there is no format difference.

Neither is better than the other.  The only difference between the two formats is the way they save information and how the start and stop points are different on the disc.  Other than that there is no difference, but be aware of what type your DVD drive is compatible with.  A DVD+R drive cannot write to a DVD-R disc and the reverse is true.  Most modern drives are DVD+/-R/RW which means they support all formats but older drives were either -R or +R and you were restricted to that format.\n\nAlso -R or +R are write once DVDs whereas -RW and +RW are write, erase and write so they can be used multiple times.
