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!

Background:\n\nDVD-R and DVD+R are both single layer, although they are composed of 2 disks glued together; one for recording and the other as a stability layer. DVD+ has the ability to support dual layer disks, but they must have DL after it (i.e. DVD+R DL).  Dual layer DVDs hold 8.54 GB and DVD's hold 4.7 GB, which is about 4.38 Gigs on a computer because DVDs are measured differently. DVDs spin about 3 times faster than CDs, allowing a larger data rate, making them optimal for video.  By the way, DVD means Digial Versitile Disk.\n\nAnswer:\n\nThe DVD- format was set up by a group as the "standard".  DVD+ disks are rivals of the DVD- format, and therefore are not considered as an official format, but they work in most situations.  The + disks are engineered differently and are considered track better and write better.  Again, the + system will SUPPORT Dual Layer, but it must be labeled with a DL.

DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media. \n\nI like your style, dont know what it is but i want one. lol\n\nHope this helps.\n\nGood Luck.

A DVD R/W will definately work on a DVD -R Writer. U can also do a multi session on the Disk.Make sure to BURN the DVD's at a lower speed over the recomended Speed. this would ensure error free writing.

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.

They're simply two different competeing formats that developed from two separate consortiums of manufacturers.  -R was the original (developed by Pioneer) and had better compatibility with existing DVD players at the time but this gap has been closed.  +R was developed by Ricoh, Sony and a few others, and came out about 1 year after -R.\n\nI believe there are some differences in the reflectivity of the two formats, since -R only writers cannot burn +R discs and vice-versa.  The main advantage of +R is that all of the current writers support burning up to 16x (only on 16x media - I've only seen -R burners go up to 8x).  Also, I believe dual-layer media is +R format only, but I'm not 100% sure.\n\nToday, other than burn speed, the point is moot since every writer on the market supports both formats and nearly all recent DVD players will read either format (including dual-layer).  Cost of the media between the two formats is about the same as well.

the only real difference is if the DVD player you want to play the disks back on support that format or not. you can use any on your PC but might not be able to play back on your DVD player. if you want to be able to re use the disks you will need +RW or -RW. if you just want to record something for keeping then +R or -R which are cheaper are fine. the 4x 8x  etc refer to the speed at which you can record onto them you can use any speed you want but your drive will only work up to its max speed, +/- R are faster than +/- RW.

I had a tech at a computer store at my hometown explain the difference....... One is developed using a spiral circular formation and another is from the inside out..its hard to explain really in a sence..but if u want to know which one to burn on and have it most compatible, do the DVD+R cause more of your dvd players and driver do not support the DVD-R. I have 2 dvd burners on 2 different computers and have tested this thoeory already.

you can't do this to a dvd-r disk. What you can do is buy a brand new for a couple of bucks. This is the society of spending, so re-using something is actually not good for the system. Are you a communist?? ;-)

The R's mean that you can write data only once, and from begining to end. That basically means that if you want to write data again on the cd, you will have to reformat it, which means that u will have to erase all the stuff on it first.\n\nThe Rw's mean that you can burn a disc, then go back and add or insert data in it without acutally having to delete evrything on their previously\n\nthe + and - symbols indicate the type of formatting, the most common supported form is the '-' symbol, however many programs (including microsoft, apple, nullsoft, and megapixis) support the '+' formatting. In all honestly the formatiing shouldnt even matter, as most if not companies try to support as many as possible.

Depends on your DVDR drive`s speed.\nI usually use 8x DVD-R but record at 4x or 6x ,unless the disc is high quality.

DVD means 'Digitally Versatile Device'. It holds more capacity than a CD. A CD can hold 650MB to 700MB of data whereas a DVD can store upto 9GB of data depending on its type. Dual layered DVDs can hold more.\nDVD picture quality is better, and many of DVDs have Dolby Digital or DTS sound, which is much closer to the sound you experience in a movie theater.\nMany DVD movies have an on-screen index, where the creator of the DVD has labeled many of the significant parts of the movie, sometimes with a picture. With your remote, if you select the part of the movie you want to view, the DVD player will take you right to that part, with no need to rewind or fast-forward.\nDVD players are compatible with audio CDs.\nSome DVD movies have both the letterbox format, which fits wide-screen TVs, and the standard TV size format, so you can choose which way you want to watch the movie. \nDVD movies may have several soundtracks on them, and they may provide subtitles in different languages. Foreign movies may give you the choice between the version dubbed into your language, or the original soundtrack with subtitles in your language. \n\nThe Emprex drive that you have is capable of writing to blank CDs as well as blank DVDs. The discs that you can write to are CD-R, CD-RW, DVD R, and DVD RWs.\nHere is a link to simplify what I've said.\nhttp://www.dvddemystified.com/dvdfaq.html#4.3\nJust look at the table at the bottom.\n\nAlternatively you also maybe facing an issue with the writing software. Try another one like Nero or DVD maker.\nCheck if the Disc is empty.

The only physical difference between the formats is the way they determine the location of the laser beam on the disc. DVD-RW/R discs use tiny marks along the grooves in the discs, called land prepits, to determine the laser position. DVD+RW/R discs do not have land prepits, but instead measure the "wobble frequency" as the laser moves toward the outside of the disc.\n\nHowever, most companies have hybrid DVD drives that support both DVD-R and DVD+R formats. They are known as DVD±R or DVD±RW drives. \n\nWhen looking for media for a DVD drive, make sure it ends in "-R" if a DVD-R drive or "+R" if a DVD+R drive.\n \nIf a DVD±R drive, you can use either format. DVD-R is still more popular than DVD+R, but since they are both widely supported, it should not matter which format you choose.
