Difference between DVD-R and DVD+R
DVD-R and DVD+R are two different formats for recordable DVDs. The main difference between them lies in the technical specifications and the companies that supported each format when they were introduced.
- Compatibility:
DVD-R was developed by Pioneer, and it was the first recordable DVD format available. DVD+R, on the other hand, was developed by a consortium led by Philips and Sony as a response to DVD-R. Initially, DVD-R had broader compatibility with DVD players and burners. However, modern DVD players and burners often support both formats equally well. - Technical Differences:
Although both formats achieve similar results, they use different approaches. DVD-R uses a pre-recorded wobble frequency to synchronize the writing laser, while DVD+R uses a more complex technique called ADIP (Address in Pregroove). DVD+R also has additional features like lossless linking and real-time linking, which help improve performance during the burning process. - Booktype Setting:
DVD+R has a feature called booktype setting, which allows the disc to mimic the booktype (DVD-ROM) of commercially pressed DVDs. This can improve compatibility with older DVD players that may have trouble reading recordable DVDs. - Manufacturer Support:
Initially, there was a divide in manufacturer support, with some companies favoring DVD-R and others DVD+R. However, as time has passed, most manufacturers now produce drives and media that support both formats.
Overall, for most users, the differences between DVD-R and DVD+R are minimal. Both formats offer similar performance and compatibility in modern DVD players and burners. When choosing between the two, it's often more important to consider the compatibility of the specific DVD player or burner you'll be using rather than the format itself.
