Why DVD+R(W) is superior to DVD-R(W) -

What is DVD

" DVD (also known as "Digital Versatile Disc" or "Digital Video Disc") is an Optical Disc Storage media format that can be used for data storage, including movies with high video and sound quality. DVDs resemble compact discs as their physical dimensions are the same (12 cm (4.72 inches) or
occasionally 8 cm (3.15 inches) in diameter) but they are encoded in a
different format and at a much higher density. The official DVD
specification is maintained by the DVD Forum. "

DVD+R

A DVD+R is a writable optical disc with 4.7 GB (4.38 GiB) of
storage capacity (actually 2295104 sectors of 2048 bytes each). The
format was developed by a coalition of corporations, known as the
DVD+RW Alliance, in mid 2002. Since the DVD+R format is a competing
format to the DVD-R format, which is developed by the DVD Forum, it has
not been approved by the DVD Forum, which claims that the DVD+R format
is not an official DVD format.

In October of 2003, it was demonstrated that double layer technology
could be used with a DVD+R disc to nearly double the capacity to 8.5 GB
per disc. Manufacturers have incorporated this technology into
commercial devices since mid-2004 (E.g DVD+R DL).

Unlike DVD+RW discs, DVD+R discs can only be written to once. Because
of this, DVD+R discs are suited to applications such as nonvolatile
data storage, audio, or video.

The DVD+R format is divergent from the DVD-R format. Hybrid drives
that can handle both, often labeled "DVD±RW", are very popular since
there is not yet a single standard for recordable DVDs. There are a
number of significant technical differences between the dash and plus
formats, and although most consumers would not notice the difference,
the plus format is considered by some to be better engineered.

Like other plus media, it is possible to use bitsetting to increase the compatibility of DVD+R media.

As of 2006, the market for recordable DVD technology shows little
sign of settling down in favor of either the plus or dash formats,
which is mostly the result of the increasing numbers of dual-format
devices that can record to both formats; it has become very difficult
to find new devices that can only record to one of the formats.
