What is the difference between DVD+R/RW and DVD-R/RW?

Answer 1

DVD-R discs include a small, pre-recorded ring used for data encryption. No, not in a good way: These discs take longer to copy and, in some cases, can't be copied at all due to the pre-recorded crypto ring, which can't be overwritten. (The upshot is that this can prevent "disc-at-once" copying, or a complete bit-for-bit copy, because a portion of the disc is un-writeable.)
DVD+R does not.

Answer 2

The truth is that the two competing technologies use different formats. No single company "owns" DVD and both technologies have their "champions".

DVD+R/RW is also based on CD-RW technology. DVD+R/RW is supported by Sony, Philips, HP, Dell, Ricoh, Yamaha, and others, and has recently been endorsed by Microsoft. DVD+R/RW is not supported by the DVD Forum, but the Forum has no power to set industry standards, so it becomes a market-driven issue

DVD-R/RW was developed by Pioneer. Based on CD-RW technology, it uses a similar pitch of the helix, mark length of the 'burn' for data, and rotation control. DVD-R/RW is supported by the DVD Forum, an industry-wide group of hardware and software developers, and computer peripheral manufacturers. The DVD-R format has been standardized in ECMA-279 by the Forum, but this is a private standard, not an 'industry' ISO standard like the CD-R/RW Red Book or Orange Book standard.

Answer 3

It's the format of the DVD, from two different brands

If you have a DVD-R-RW drive, you only can burn - DVDs
If you have a DVD+R+RW drive, you only can burn + DVDs
If you have a DVD±R±RW drive, can burn both formats

If your drive says DL then you can burn DL9 or dual layer DVDs 8.5 GB

Answer 5

DVD+R/RW = you can read/write +R/RW DVD type
DVD-R/RW = you can read/write -R/RW DVD type

-R is much compatible with TV standalone DVD players.
+R is better for computers only.
so if you wanna be sure your DVD is ok to see it on all DVD players use -R type.

Answer 6

It's the way that it burns the disk. I think one changes the shape of the surface (photosensitive). While the other burns small layers in the surface.
