Hi shabash,
Question: What is the difference between the DVD-R and DVD+R formats?
Answer: "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 was developed by Sony and Philips and was
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."
