what is the difference between DVD+R and DVD-R?
94305
It's more of a difference in the media type.  DVD-R is not compatible with DVD+R drives and DVD+R is not compatible with DVD-R drives.  However, if you buy a DVD-/+R drive, then both medias will work.  DVD+R are cheaper usually.\n\nThe DVD-R standard was formed by Time Warner, Mitshubishi, Sony and Hitachi.  DVD+R was formed by DVD+RW Alliance i.e.  Sony, Yamaha, Philips, Dell, and JP.\n\nIt's more of a "securing market share" move.  However, now most drives are DVD-/+R drives.  So, the difference is not that noticeable

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-ROM is a dvd drive, DVD-RAM is a type of DVD http://en.wikipedia.org/wiki/DVD-RAM\nthat can be burned too.  DVD+/-RW is more common.  If you just bought the computer and it is a new computer, you have a DVD-rom drive or a DVD+RW or -RW drive.  DVD-RAM isn't really that common anymore.  Easiest way to check what you I have I have found is to either go check your system components in the control panel, look at your invoice or open up your burning software, odds are if it gives you the option to burn a DVD you have a DVD RW drive and you should just see if it is a + or - RW drive cause their are different blank DVD's to use for each

DVD+R and DVD+RW\nDVD+R and DVD+RW formats are supported by Philips, Sony, Hewlett-Packard, Dell, Ricoh, Yamaha and others. \n\nDVD+R is a recordable DVD format similar to CD-R. A DVD+R can record data only once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time. \n\nDVD+RW is a re-recordable format similar to CD-RW. The data on a DVD+RW disc can be erased and recorded over numerous times without damaging the medium. \n\nDVDs created by a +R/+RW device can be read by most commercial DVD-ROM players. \n Key Terms To Understanding DVD Formats\nDVD\nShort for digital versatile disc or digital video disc, a type of optical disk technology similar to the CD-ROM. \n\nDVD-Video \nA video format for displaying full-length digital movies. \n\nDVD-ROM \nA type of read-only compact disc that can hold a minimum of 4.7GB (gigabytes), enough for a full-length movie. \n\nburn\nSlang term meaning to write data to a CD-ROM or DVD-ROM.\n\nDivx\nShort for Digital video express, a new DVD-ROM format promoted by several large Hollywood companies. With Divx, a movie (or other data) loaded onto a DVD-ROM is playable only during a specific time frame, typically two days. \n \n\nDVD-R, DVD-RW and DVD-RAM\nThese formats are supported by Panasonic, Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung and Sharp. These formats are also supported by the DVD Forum. \n\nDVD-R is a recordable DVD format similar to CD-R and DVD+R. A DVD-R can record data only once and then the data becomes permanent on the disc.

They are both the same, along with CD+R/W  it just means that one u can use over and over again and the other you can right to just once.  both hold 700MB. Your program u use to burn your data, there is always setting to "Overburn" but it can damage the disc or the drive.

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.

They're the same physically but the difference is how they get written.\n\nSome more information here\nhttp://www.worldstart.com/tips/tips.php/777\n\nAlso you can buy DVD's online...from say... http://www.w2w.com\n\nnm4887...Please tell me where DVD-RW is even mentioned in the question? geez!\n\nAND NO IT DOESN'T MEAN ITS REWRITABLE.\nYOU ARE TALKING ABOUT DVD+RW/DVD-RW!\n(to the guy below me)

different formats.\n\n- is more common, but the + is beter quality.\n\nThe + takes records data on a stream, which makes it easy to record on, so, if you have a recordable DVD player, these are the kinds to go for.

dvd+ is DVD+R/RW and dvd- is DVD-R/RW...\n\nDVD-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.\n\nDVD+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.

PC - In my experience the best software is Nero.  But your computer probably already came with something like Roxio.\n\nAnyway, as far as +/-.... I prefer the MINUS.  In my experience a greater number of DVD Players accept the minus discs (especially the older ones).  If you are just archiving data... there's probably no noticeable difference.

DVD /CDROM and Hard disks are different media. The way they are designed and how they are made are different. The software which sets up the hardware is the driver. Since the hardware is different the programming model (i.e. list of instructions to setup the hardware ) also is different. \n\nFor example DVD has much more features than a regular hard drive. It has support for error correction which is superior\nThat is the reason the drivers are completely different.
