DVD-R (pronounced "DVD dash R") and DVD+R (pronounced "DVD plus R") are nearly identical formats. The discs look the same and are both supported by most DVD-ROM drives and DVD burners. The only difference between the formats is the way they determine the location of the laser beam on the disc. DVD-R discs use tiny marks along the grooves in the discs, called land prepits, to determine the laser position. DVD+R discs do not have land prepits, but instead measure the "wobble frequency" as the laser moves toward the outside of the disc.
The DVD-R format was developed by Pioneer and was released in the second half of 1997. DVD+R were developed by Sony and Philips and were introduced in 2002. Companies that support DVD-R include Pioneer, Toshiba, Hitachi, and Panasonic, while companies that support DVD+R include Sony, Philips, Hewlett-Packard, Ricoh, and Yamaha.
However, most of these companies now develop hybrid DVD drives that support both DVD-R and DVD+R formats. They are known as DVD?R or DVD?RW drives. When looking for media for your DVD drive, make sure it ends in "-R" if you have a DVD-R drive or "+R" if you have a DVD+R drive. If you have 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.
What is the difference between burning and ripping?
"Ripping" refers to extracting audio files off a CD and copying them to your hard drive. After ripping the audio, you can then convert the files to the more compressed MP3 format if you want. "Burning" refers to the process of writing data onto a CD. You can burn both audio and data CDs, as well as DVDs, provided your computer has a CD/DVD burner.
