what is the difference between DVD+R and DVD-R?

Answer 1

They're basically diffent formats. They do the same thing but are incompatible. However, almost all DVD burners today are multi-format, which means that they will accomodate both types of DVDs. However, if you're buying an older burner or computer with a burner, you may be only able to use one type.

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 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.

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.

Technical Answer

DVD+R is a dvd disc that allows multiple layers for one disc where as dvd-r only allows one layer. They will not compete to become the de Facto standard, because they are both here to stay. Multi layer DVD+R can allow extra capacity per disc than DVD-R hence its high cost!

Answer 3

all the answers are wrong

The answer is its a bit like beta vs vhs. 2 different formats. DVD-r came out befor DVD+R. In the end they both act the same, but certain burners will only cope with one or the other (though modern burners often cope with both). Dvd PLAYERS often again will only play one or the other....it depends how cheap your DVD is.

As for physical difference, the 2 formats actually burn to the dvd differently, I forget how, I'll look it up in my book if I can be botherd and amend this.

So dvd-r is not dvd+r.....or they would be labelled the same thing!!!!

yes the person saying dvd+r is double layerd is incorrect... you can buy dvd-r and dvd+r single layed (4.5-4.7 GB) or dual layerd (twice the size on one disc)

Answer 4

DVD+R is a dvd disc that allows multiple layers for one disc where as dvd-r only allows one layer. They will not compete to become the de Facto standard, because they are both here to stay. Multi layer DVD+R can allow extra capacity per disc than DVD-R hence its high cost!

Answer 5

I went though that about a year ago at my job. DVD+R are for newer DVD players. DVD-R are for older DVD players. My dream would be for there to be DVD+-R. Then it works for everyone. You really have to test which one will work for your system.

Answer 6

I may be wrong or this might not be complete, but I think that DVD-R is for more basic things as burning movies and videos. DVD+R is double layer for more complex things as multimedia presentations.

Answer 7

dvd+r is multisision but -r is not
it means dvd+r can read a type of dvds that -r can not read them.

Answer 8

Dvd+R means it has a recorder and DVD-r means it doesn't have a recorder

Answer 9

the format of the disk, the - r holds a little more, but cannot be played in all devices

Answer 10

something having to do with burning, but i dont think there is a difference
