Question

What is the difference between the DVD-R and DVD+R formats?

Answer 1

DVD-R is a DVD recordable format. A DVD-R typically has a storage capacity of 4.71 GB (or 4.39 GiB), although the capacity of the original standard developed by Pioneer was 3.95 GB (3.68 GiB). Both values are larger than the storage capacity of its optical predecessor, the 700 MB CD-R.

A DVD+R is a once-writable optical disc with 4.7 GB (4.377 GiB) of storage capacity (more precisely, 2295104 sectors of 2048 bytes each). It has slightly less storage capacity than the DVD-R (4.382 GiB). The format was developed by a coalition of corporations, known as the DVD+RW Alliance

Answer 3

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.

Answer 4

with the help of DVD-R in SL(single layer) you can allocate more space in your dvd comparing to DVD+R which can write 4.377GB whereas DVD-R can write upto 4.382GB.

and also if in case of DL(Double layer) version it is merely opposite DVD-R will allocate less space than DVD+R which can write 7.961 out of 8.5 Gb whereas DVD-R can write upto 7.857 only
