DVD-R vs. DVD+R: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 17, 2023
DVD-R is a write-once format supported by the DVD Forum, while DVD+R is also a write-once format, but backed by the DVD+RW Alliance.
Key Differences
DVD-R and DVD+R are two different types of recordable DVD formats that, at a glance, appear very similar. DVD-R was the first write-once format that was developed and was formally approved by the DVD Forum, an international group of hardware and software companies. Conversely, DVD+R came about as a result of the DVD+RW Alliance, a group of corporations that believed they could improve upon the original DVD-R specifications.
While the main distinction between DVD-R and DVD+R initially arose from different supporting entities, there are technical differences as well. Specifically, the manner in which each format handles defect management and the way they format and rewrite data diverges. DVD+R, for instance, has more robust error management systems than DVD-R, which can be particularly useful when archiving or sharing data.
Compatibility used to be a primary concern for users choosing between DVD-R and DVD+R. Earlier, certain DVD players and drives could only read one of these formats. However, as technology evolved, many modern DVD players and computer drives became capable of playing both formats, diminishing the compatibility concern. Still, if someone has an older DVD player, it might be more compatible with DVD-R discs than with DVD+R discs.
A notable feature of DVD+R is the ability to add data in multiple sessions, even if the disc is not finalized. This means users can add data in separate instances until the disc is full. In contrast, with a DVD-R, the user often has to finalize the disc, which means no additional data can be added afterward. In the context of practical application, someone using a DVD+R for data storage might find this feature especially advantageous.
