CD-R, CD-RW, CD+R, etc. What do these mean?

Answer 1

CD-R - CD-R drives record up to 650 MB of data onto specialized CD-R media. The media is more expensive compared to the mass-produced CDs that software is generally distributed on, but cheap for the amount of data you can store on it. CD-R media is a WORM technology. You can Write to it Once and Read Many times, but you can't erase anything you've written.

CD-RW - A CD-ROM format that not only reads standard CD-ROMs, but can read and write CD-R disks, and also read and re-write CD-RW media. CD-RW media is more expensive than CD-R media, but it can be written to more than once in the same location, much like a hard drive or floppy disk on a computer. Standard CD-RW disks store up to 640 MB of data, similar to CD-ROM and CD-R disks.

CD+R :An incorrect designation for CD-R recordable discs and drives. There are "plus R" DVD drives, but not "plus R" CD drives

Answer 2

CD-R means Compact Disc Recordable - means you can record on the disc and record only.

DC-RW means CD Re-Writeable -means you can record on the disc and then erase it and record again for as long as the disc lasts.

CD+R - is a CD recordable however the + are slightly differently formatted to allow compatibility with certain CD recordable drives.
