Different kinds of DVDs are available in the market, each one different from the other. Explained here with important differences are two such types – DVD-R and DVD+R.
DVD, which is also referred to as digital video disc or digital versatile disc, is used for storage of data. They are very much similar to CDs, but they have a capacity to store six times more data than the CD.
Since its storage capacity is more than that of the CD, it is preferred by many people. It can be used for the storage of word and text files and software. You can also burn different games on DVDs, so that you can play these games anytime, anywhere.
In a head-to-head match, DVD+R is definitely better than DVD-R, in almost all the aspects. Though there is no physical difference between these two, a few functional differences make the former different from the latter. These few differences are given here.
The data once written on DVD-R cannot be later deleted, edited, or replaced. It was the first recording format that was compatible with DVD players and is similar to CD-R.
You can remove the DVD immediately without having to wait for the formatting. You can record one DVD+R disk partially on the computer and partially on the television. While you are formatting the disk, you can record on the part of the disk which has already been formatted. You can edit movies, song titles, play lists, and file names.
