cd-r is made to write data once.\ncd-rw was made to overwrite data more than once with the option to completely format disc

most DVD burners will copy both. just as long a you use the right CD. I use CDRW to copy games and music. If you burn dvd's you have to use the dvd disk

CDRoms are for CDs...DVDRoms are for DVDs that's why they are printed the way they are when you look at the back of the disc and such.\n\nCDs are compact discs and save information differently than the DVD, Digital Video Disc.  think of it as saving the file as a different file type.\n\nSince the CD does not recognize the "file type" that is the mechanical version of a screen that pops up and asks you to select a different program to open the file with.

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.

If you use a CD-R, put files on it,it becomes read only and the files can not be changed. \n\nHowever, if you use a CD-RW (and have a CD-RW drive), you can format the CD-RW as if it is a gigantic floppy disk, and write files to it, delete them, re-write, etc. \n\nYou will need software for formating the CD-RW, but that should be included as part of the burning software program that came with your CD burner.  Check the Helps in the program.

CD-R are called write once/read many (WORM) discs.  Erasing a disc requires you to be able to write on it more than once.  If you want to use your discs over you need CD-RW discs are mentioned above.

Well the RW means you can rewrite over and over.\nThe +R and -R means it can only be written to once.\nI'm not 100% sure but I think -R means the dvd needs to be finalized for other dvd players to be able to read it. If anyone knows for sure please correct me.

If you don't really need this database and the point is that you're going to use this RW once again - just use NERO's (or whatever CDRW-soft you use) feature "clean CD-RW". Tadam! Here we have a brand new CD-RW ready for burning once again.

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.

R=recordable\nRW=rewritable\n\nyou must have a drive that work with the cd though, it must say r or rw and it must say dvd not just cd

The + and - of the DVD R are two competing formats, +R being developed by the DVD+RW Alliance, and -R being devloped by DVD forum. Both allow recording of up two 4.7GB on a single layer, and 8.5GB on a dual layer.  The primary difference is some drives do not read one type of the DVD, and so dual drives are popular, since they can read both formats. Dual burners are also popular.\n\nAs far as I know, there is no difference in burnable CDs, A CDR is a CDR, there’s one format. Different types of CDs react differently in different drives (older drives sometimes have trouble reading certain media), but there is no format difference.

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!

Yes, u need a burner to put pictures onto a CD.\n\nA CD-R and CD-RW are essentially the same thing.\n\nCD-R: able to burn onto once and keep adding until full.\n\nCD-RW(re-writable): able to burn and erase, also keep adding until full.

For CD-RWs, it's all or none. You can't pick and choose which files to add or remove from it once it's burned. If you want to put more things on there, or remove things, you're going to have to erase it and start over. You should be able to do this in whatever application you're using to burn your CD-RWs.

The first layer of a dual later DVD disc is transparent to the laser that writes to the disc. Thereby, it is able to write to the equivalent of two disc surfaces. The RW stands for re-writable. On a normal (R) disc, the laser burns information to a disc. The disc comes from the manufacturer with all zeros on it. All the laser does is burn 1's onto the disc and this burn is permanent. An RW laser rearranges pre-existing 1's that are not really readable by the drive until they are arranged to be seen.
