Answer 2

They are two different hardware implimentations of the DVD standards.
DVD-RW was invented first for use with DVD players.
DVD+RW appeared a couple years later as DVD burners were appearing in home computers. It was made with a less expensive process so the while -RW disk were selling for $2-3 each, the +RW were selling for pennies. However not all DVD players could read the +RWs.

Today, the majority of computer DVDs and DVD players can use either. And prices for them are usually the same. Because there as still some older DVD players that only did -RW, it is still the preferred media for movies.

However either will hold movies or data just as well as the other. Rather then choosing between - and +, it is better to choose between brand names. Each brand makes their disc slightly differently. Check the web site of the manufacturer of your burner to see which brands they recommend.

The recording layer in DVD-RW and DVD+RW is not an organic dye, but a special phase change metal alloy, often GeSbTe. The alloy can be switched back and forth between a crystalline phase and an amorphous phase, changing the reflectivity, depending on the power of the laser beam. Data can thus be written, erased and re-written.

Answer 4

Not much really except that each is a different standard. Some home DVD players will only support one or the other. You should reference which device you are wanting to use the media with.

Now for movies.... DVD+R and DVD+RW are best only if your recorder/burner supports bitsetting, which is a way of specifying what kind of booktype you want the +R to look like.

Plain English: Booktype DVD-ROM is what commercial movies are pressed to. If you can bitset your recorder/burner to DVD-ROM and you burn with a DVD+R the end result is that a stand-alone player will see this +R as if it's a commercially pressed DVD-ROM.

Answer 5

A DVD-RW is a rewritable optical disc with equal storage capacity to a DVD-R, typically 4.7 GB. The format was developed by Pioneer in November 1999 and has been approved by the DVD Forum. Unlike DVD-RAM, it is playable in about 75% of conventional DVD players.

The primary advantage of DVD-RW over DVD-R is the ability to erase and rewrite to a DVD-RW disc. According to Pioneer, DVD-RW discs may be written to about 1,000 times before needing replacement, making them comparable with the CD-RW standard. DVD-RW discs are commonly used for volatile data, such as backups or collections of files. They are also increasingly used for home DVD video recorders. One benefit to using a rewritable disc is if there are writing errors when recording data, the disc is not ruined and can still store data by erasing the faulty data.

One competing rewritable format is DVD+RW. Hybrid drives that can handle both, often labeled "DVD±RW", are very popular since there is not yet a single standard for recordable DVDs.

The recording layer in DVD-RW and DVD+RW is not an organic dye, but a special phase change metal alloy, often GeSbTe. The alloy can be switched back and forth between a crystalline phase and an amorphous phase, changing the reflectivity, depending on the power of the laser beam. Data can thus be written, erased and re-written.

Answer 6

DVD-RW (The Rewrittable version of DVD-R) became the unique ReWrittable DVD progressed by using Pioneer and DVD+RW became yet another format of ReWrittable DVD (the rewritable version of DVD+R) supported by using Philips/sony and others. click on the link under for extra...

Answer 7

The -RW is better quality, but the +RW are compatible with most all dvd players and burning programs.
Go with +R if you aren't sure what u need.

Answer 8

i think one play movies and one doesn't play movies
