A DVD-R is a DVD recordable format, with the ability to store aprox 4.7GB of data within the disc. DVD+R are only able to record data one, for it to be then permanent on the disc.

DVD+R's work very much similar to a normal DVD, though in comparison to a CD-R, they've a larger storage capacity; due to a smaller pit size and smaller track pitch. In turn, more pits can be written upon the same physical sized disc.
