In today's advanced technological world, the term 'DVD' is not something that needs to be explained. Most people not only know about DVDs, but also use them in their everyday lives. Though used so very often, very few people know the actual difference between DVD-R and DVD+R, which are formats of Digital Versatile Discs(DVDs). When it comes to the difference between DVD-R and DVD+R, a majority of people think that the functions and technologies used in these discs would be much different. However, you need to know that there is not much of a difference between these two data storage mediums.
The 'R' after the plus or minus indicates 'recordable', which means that the disc can be written upon, but only once. If you have an 'RW' after the plus or minus sign, it indicates a 'rewritable' disc, which means that the disc can be rewritten up to 1,000 times. There is no difference between DVD-R and DVD+R in terms of the storage capacity they provide. A single layer DVD of both formats has a capacity of 4.7 GB, and a dual layer DVD has a storage capacity of 8.5 GB. Read more on different DVD formats.What is the Difference Between DVD-R and DVD+R?
Ownership of the DVD Formats
DVD-R and DVD+R are two contending technologies which employ different formats. Each of these formats is formally sanctioned and backed up by their individual forums. These licensing forums comprise of a particular number of companies. A company named 'Pioneer' was responsible for the advent of the DVD-R format which is based on the same technology as a CD-R. The DVD-R format is backed up by the 'DVD Forum' which was established by companies such as Mitsubishi, Sony, Hitachi, and Time Warner. It is believed that Sony Corporation took the initiative of developing the DVD+R format. This format is also no different from the CD-R. The DVD+R format is backed up by the 'DVD+RW Alliance'. This authorizing entity comprises of member companies which include Sony Corporation, Yamaha Corporation, Philips, Dell, and some others.Technology Used in the DVD Formats
The primary divergence amongst these two optical data storage discs is the inherent technology which is normally unobtrusive to the user. DVD-R employs the Land Pre Pit (LPP) technology for tracking and controlling the speed, whereas DVD+R utilizes an advanced ADdress In Pregroove (ADIP) functionality which makes the operation more precise at higher speeds. When it comes to the technology in DVD-R and DVD+R formats, the latter one uses a more robust error management technology than that employed in the former. The DVD+R format also employs more precise session linking methods which contribute to fewer damaged discs than the DVD-R format.Finalization of DVD-R and DVD+R
Another significant point of difference between DVD-R and DVD+R is that a DVD-R can be used in only one session for writing, while a DVD+R can be used in multiple sessions. In simple terms this just means that once you have used a DVD-R for writing data, it cannot be used again to write anymore data, even if there is space remaining on the disc. In case of a DVD+R, multiple sessions are allowed, meaning you can write 2GB in one session and still use the disc to write more data, till the entire capacity of the disc is used. In technical terms, this is called finalization of the disc. DVD-Rs finalize after a single burn, while DVD+Rs allow you the option of creating a 'multisession disc' instead of finalizing after the first burn. 'Multisession discs', however, may not be compatible with all players and DVD drives.Compatibility with DVD Players
The most significant aspect to consider about the difference between DVD-R and DVD+R formats is that the former one was developed first. This means that almost every DVD player or burner is compatible with DVD-R discs. So if you are not sure about where the disc is going to be used, it is recommended to store data on a DVD-R disc, as it can be played on most DVD players. You also need to take in mind that along with the compatibility factor, DVD+R discs are a bit more expensive that DVD-R discs. Read more on:

There is no physical difference between these two discs. The only time you will possibly ever come to know a difference between DVD-R and DVD+R discs is if you insert a DVD+R in a drive that is only compatible with DVD-R discs. If you want to play both types of discs on a single DVD drive, you need to purchase a hybrid DVD drive which is generally marked as DVD±R. If you are thinking of DVD-R vs DVD+R, which is better depends on the technology you are looking for. DVD+Rs are more expensive, and even though they may be superior to DVD-Rs, they will not work on all players. DVD-Rs are a safer bet, are cheap, and will work on all players, though they may lack some minor features of DVD+Rs. The choice is yours!
