There is a lot of confusion between DVD-R and DVD+R as they have similar names, and they also have the same function and a lot of other similarities.
Until now, many of you thought that both DVR-R and DVD+R are the same; while they can have many things in common, they are not the same.
Key Takeaways
- DVD-R is a recordable DVD format that uses a “dash” or “minus” notation, adhering to the standards established by the DVD Forum and widely compatible with most DVD players and drives.
- DVD+R is another recordable DVD format that uses a “plus” notation, developed by the DVD+RW Alliance, offering some technical advantages over DVD-R, such as better error management and faster writing speeds.
- Both DVD-R and DVD+R are recordable DVD formats, but DVD-R follows the DVD Forum standards and is widely compatible, while DVD+R is developed by the DVD+RW Alliance, offering some technical improvements.
DVD-R vs DVD+R
The difference between DVD-R and DVD+R is between their formats and how they control the laser beam’s location on the disc.
DVD-R is an optical disc recording technology or DVD recorder. It gives higher storage capacity. Pioneer developed this in 1997. This format is supported by standard DVD players and in approved DVD forums.
DVD-R provides broad playback compatibility with old players. It is more like a CD-R, but it has more storage capacity.
DVD+R stands for Vertical Disc Recordable; it looks more like a standard DVD. The “R” format in the disc is suitable for retaining data such as video, audio, and pictures. Both DVD-R and DVD+R look pretty similar.

What is DVD-R?
DVD-R is also known as a digital versatile disc recordable. It looks the same as a regular DVD; it records data like CD-R.
If the DVD-R gets burned, then you can’t use it to rewrite the data again. A single-sided, single-layer disc has a storage capacity of 4.7GB of data, and a double-sided or double-layer disc has a storage capacity of 8.5 GB.
It is the most common format of a writable DVD. DVD-R can be read mainly by all DVD players and DVD ROM.
You can use DVD-R to back gigabytes of data on your PC and make your video DVD. The Apple company computer also supports the DVD-R format.
Its format is very similar to CD-R. DVD-R can record data once, which is permanent in a disc. You cannot register on that disc for the second time.
Two additional DVD-R standards are DVD-RG, which is useful for general purposes, and DVD-RA, which is useful for mastering DVD video, not available for the normal public.
Worldwide famous companies such as Panasonic, Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung, and Sharp support this format type. It is also supported in the DVD forum. This format is cheaper than DVD+R.
What is DVD+R?
DVD+R stands for versatile disc recordable. It looks the same as a standard DVD, there is no physical difference between them, but it can record data.
Single-sided and single-layer DVD+R have a storage capacity of 4.7GB of data, and on the other hand, double-layer discs have a storage capacity of 8.5GB, and double-sided have 9.4 GB.
This format is not very common, like DVD-R, but many DVD players and DVD-ROM drives still support it. It is one of the most expensive formats made by Sony and Philips and used by companies like Sony, Philips, Hewlett-Packard, Ricoh, and Yamaha.
A drive that reads both DVD+R and DVD-R is known as a DVD—r drive. DVD+R can record DVDs partially on TV and partially on PC, and this format can also rename the file name, movie playlist, and song titles. It is a rewritable disc that can erase data and rewrite it.
Main Differences Between DVD-R and DVD+R
