What is the difference/applications between dvd-r and dvd+r discs?

there's no difference between dvd-r and dvd+r disks. Some manurfacturers will put either + or -, but essentially the R just means recordable. You can only record on this type of media once.If you wanted to back up that could never be changed then you would use the recordable.  See this link for further details: \nhttp://www.dvdforum.org/tech-dvdprimer.htm#6

If you have a DVD+/-R drive, you can read the disk off a +R disk and copy it to a -R disk.  Check in your DVD burner software for a "disk Copy" utility.

If it is a rewritable DVD (DVD RW), it must be formatted before you can put files in it. If it is just a write once DVD (DVD R), formatting is NOT needed.\n\nOne VERY important piece of info that you MUST know is what type of DVD media your burner can read/burn. This is something that a lot of people do not immediately pay attention to.\n\nThere IS a difference as to whether or not your drive can burn to a DVD +R or a DVD -R. If you can only burn to a +R and you stick in a -R DVD in there, it will not recognize it. As such, also be sure that your rewritables are of the appropriate code (DVD +RW or DVD -RW) or dual (DVD +/- RW)\n\nHope this helps.

DVD +R DVD -R DVD+RW DVD-RW\n\nthe diffrence between a +R and a -R is when coming to record a dvd movie... the +r comes out with a slight better quality then - R thought it is only noticable on a LCD Screen\n\nThere is also +RW and -RW same as above but they can be rewritten on

CD-R is a blank, recordable cd that holds up to 700mb. It is NOT rewritable\n\nCD-RW is the same as a CD-R, but it can be rewritten.\n\nDVD-R is a format of DVD, sometimes more compatible with older DVD players.  It holds 4.7gb (~4700mb).  There is also a rewritable version of this named DVD-RW\n\n\nDVD+R is another format of DVD, it can also hold 4.7gb.  There are rewritable versions of this that are DVD+RW.\n\nDVD-DL is another DVD format in which there are two layers.  This doubles the capacity of the DVD so it can hold 8.5 gb (~8500mb).  These are newer and more expensive in the consumer market; however, almost all of the DVD movies you have in your home are printed on DVD-DL.\n\nI hope I helped!

Actually, most DVD drives will handle faster discs, and will just burn them at the lower speed.  But, if you're fixed on getting 4X DVD+R blanks, you might try going to Newegg's website and ordering them from there.  Here's a link for you and you can go from there:\nhttp://www.newegg.com/Product/ProductList.asp?N=2010100071+1087408097&Submit=ENE&SubCategory=71

CD-RW writes only CDRoms with max capapcity of 700mb, while DVD-RW writes DVD disks up to 4.7gb and up to 8bg on Double-Layered DVD disks. \n\n4.7gb DVD blanks are more common. Commercial studios publish their movies to 8gb DVD disks.  They usually have more than sufficient space to throw in extras like interviews, making of the movies and so on.\n\nWhen you want to legally backup your copy of DVD movies you have to shrink the movies from 8gb down to 4.7gb to fit. VCD and SVCD format of up to 1150bps may be burned to multiple CDRoms, while DVD have a higher cinematic quality of anything from 5000bps to 9000bps and need only 1 disk to contain a whole movie.\n\nBurning Movies to DVD quality is the only way to go these days.\n\nNow the latest technology is Blu-Ray disc with capacity of up to 20gb. Wouldn't be available for a while though.

DVD-R\nA DVD-Recordable or DVD-R (pronounced "DVD Are" or "DVD Dash Are") is an optical disc with a larger storage capacity than a CD-R, typically 4.7 GB (4.38 GiB) instead of 700 MiB, although the capacity of the original standard was 3.95 GB. Pioneer has also developed a 8.54 GB dual layer version, which appeared on the market in 2005. A DVD-R can be written to only once, whereas a DVD-RW (DVD-rewritable) can be rewritten multiple times.\n\nThe DVD-R format was developed by Pioneer in autumn of 1997. It is supported by most DVD players, and is approved by the DVD Forum.\n\nA competing format is DVD+R (also DVD+RW for the rewritables). Hybrid drives that handle both formats are often labeled DVD±R and Super Multi (which includes DVD-RAM support) and are very popular.\n\nThe larger storage capacity of a DVD-R compared to a CD-R is achieved through smaller pit size and smaller track pitch of the groove spiral which guides the laser beam. Consequently, more pits can be written on the same physical sized disc. In order to write smaller pits onto the recording dye layer (see CD-R) a red laser beam with a wavelength of 650 nm (for general use recordable DVD) is used in conjunction with a higher numerical aperture lens. Because of this shorter wavelength, compared to CD-R, DVD-R and DVD+R use different dyes to properly absorb this wavelength.\n\nDVD-R discs are composed of two 0.6 mm polycarbonate discs, bonded with an adhesive to each other. One contains the laser guiding groove and is coated with the recording dye and a silver, silver alloy or gold reflector. The other one (for single-sided discs) is an ungrooved "dummy" disc to assure mechanical stability of the sandwich structure, and compatibility with the compact disc standard geometry which requires a total disc thickness of about 1.2 mm. Double-sided discs have two grooved, recordable disc sides, and require the user to flip the disc to access the other side. Compared to a CD's 1.2 mm of polycarbonate, a DVD's laser beam only has to penetrate 0.6 mm of plastic in order to reach the dye recording layer, which allows the lens to focus the beam to a smaller spot size, which is key for writing smaller pits.\n\nIn a DVD-R, the addressing (the determination of location of the laser beam on the disc) is done with additional pits and lands (called land pre-pits) in the areas between the grooves. The groove on a DVD-R disc has a constant wobble frequency used for motor control etc.\n\nCheck out http://en.wikipedia.org/wiki/Dvd-r for more information about DVD-R\n\nDVD+R\nA DVD+R is a writable optical disc with 4.7 GB (4.38 GiB) of storage capacity (interpreted as &#92;approx 4.7&#92;cdot10^9, actually 2295104 sectors of 2048 bytes each). The format was developed by a coalition of corporations, known as the DVD+RW Alliance, in mid 2002. Since the DVD+R format is a competing format to the DVD-R format, which is developed by the DVD Forum, it has not been approved by the DVD Forum, which claims that the DVD+R format is not an official DVD format.\n\nIn October of 2003, it was demonstrated that double layer technology could be used with a DVD+R disc to nearly double the capacity to 8.5 GB per disc. Manufacturers have incorporated this technology into commercial devices since mid-2004 (see DVD+R DL).\n\nUnlike DVD+RW discs, DVD+R discs can only be written to once. Because of this, DVD+R discs are suited to applications such as nonvolatile data storage, audio, or video.\n\nThe DVD+R format is divergent from the DVD-R format. Hybrid drives that can handle both, often labeled "DVD±RW", are very popular since there is not yet a single standard for recordable DVDs. There are a number of significant technical differences between the dash and plus formats, and although most consumers would not notice the difference, the plus format is considered by some to be better engineered.\n\nLike other plus media, it is possible to use bitsetting to increas

DVD+R's are NOT re-writeable. only DVD RW's are ReWriteable.\nthe most compatable with standalone players are DVD-R however you can only burn a DVD type that your burner supports so i'd check your DVD burner first.

CD-r burns on the bottom of the disk, where a CD+R burns on the top.  There is really no difference in terms of use.

digital video disc-recordable, (dvd+r is the same) digital video disc dynamic library, digital video disc read only memory, digital video disc re-writable, and digital video disc random access memory

Are we taling abour DVD-R and DVD-RW? what you have mentioned above seems the same. RW stands for ReWritable.

It is a format difference originally between manufactures. Now most DVD players will read either +R or -R. There is supposedly a slight useage edge for -R but ability to read is what is important. I record all my DVDs in +R and I never have a problem playing them in any DVD player. \n\nMy computer burner will burn either format but I just started using +R and that is what I usually buy.\n\nNeither a +R or a -R are rewritable. For that you want a +R-RW or a -R-RW.

To answwer your first part, any DVD player newer than two years will most likely be able to play DVD-/+R discs.  The problem is that not all DVD players from that era or even ALL new DVD players can play those formats.  So the first thing you should do is check your DVD players manual to see if it can play -/+R discs and if you need to buy a new one, check the specs to make sure as well.\n\nAs far as the technology goes, there is no difference the only difference is the start and stop points on the disc.  But for the most part data is written in the same way on the discs but it is enough of a difference that you can't read a -R disc if it only support +R and the opposite is true.\n\nSee the following for more information, http://en.wikipedia.org/wiki/Dvd-r and http://en.wikipedia.org/wiki/DVD%2BR

If it's for a desktop/external?  Look at the outside cd-tray.  It will say something like either "DVD-rom" or "DVD +/- RW" or something like that.  If it says "DVD +/- RW" or "+/- R" or any combo containing the ending of RW  or R then, yes, it's a burner.

Well, there are really only two "families" of DVD at the moment (unless you want to count the red laser vs. blue laser stuff that's starting to come on to the market at the high end), and one "outcast". You've got the "minus" ("-") formats (DVD-R, DVD-RW) and the "plus" ("+") formats (DVD+R, DVD+RW), then there's the older DVD-RAM format that's harder to find these days. All of these are for data, of course -- all but the newest DVD video players will choke on those, in the same way early CD players choked on CD-R discs. \n\nA DVD-R is a write-once format: once you've burned the data onto that DVD platter, the disk is forever frozen with that information. Add the "W" to that, and you'll find that DVD-RW can be erased or rewritten up to a thousand times. Seems kinda weird, but if you can do so, DVD-RW obviously has significant advantages over DVD-R. DVD-RAM was even more flexible, however, since it let you erase and rewrite sections of an existing DVD, something that you cannot do with DVD-RW. \n\nMoving to the plus side is where things get a bit confusing, because DVD+RW came before DVD+R. The plus formats have the same data storage capacity as the minus formats (4.7GB), but DVD+RW offers faster writing, better internal linking (a technical obscurity you don't have to worry about), and support for drag-and-drop desktop files, which makes it easy to compose the contents of a disk. DVD+R is a write-once format intended to be more compatible with more DVD players, though at this point it seems to be about even with DVD-R, which remains the most compatible computer-burned DVD format. \n\nIn your case, since your drive is a DVD-RW, you're effectively limited to DVD-R and DVD-RW format discs. Stay away from any of the "plus" formats, as those won't work with your drive (and being newer, they cost more anyway). As to whether you want to use DVD-R or DVD-RW, that depends on what you want to use them for. DVD-R is a write-once format, just like CD-R, and you can't erase the data once it's written. DVD-RW is rewritable, so you can use it somewhat like a 4.7GB floppy disc, for all intents and purposes. In general, I suggest that you use DVD-R for archival purposes -- stuff that isn't going to change, and DVD-RW for more fluid data. DVD-RW discs are more expensive than DVD-R discs, so that may also influence your decision. \n\nHow do you confirm what format your drive works with? One way, if you're on a Mac, is to use the System Profiler application. You'll find this useful utility in Applications -> Utilities. Launch it, then click on the "ATA" item on the list. If you have an internal DVD burner, you'll see something like what I get: "PIONEER DVD-RW DVD-106D". If it's an external DVD drive, you might find it in SCSI, USB or FireWire, depending on how you hook it up. \n\nAs far as your second question, your data-burning application definitely has to be aware of the DVD format you want to use (i.e. DVD-R or DVD-RW in your case). For Windows, you can use GEAR for burning CDs, but you'd need to upgrade to GEAR Professional Edition to be able to burn both CDs and DVDs. Toast Titanium does burn DVD-R and DVD-RW so you should be set in that department.
