What is the Difference Between r and -r dvds?
🆚 Go to Comparative Table 🆚The difference between R and R DVDs lies in their recording modes:
- R DVDs: These are DVD-Recordable discs that can be recorded on only once. The "R" stands for "recordable" or "rewrite" depending on the manufacturer. R DVDs are useful for creating permanent backups of data or for burning large video files that take up a lot of space.
- RW DVDs: These are DVD+RW (ReWritable) discs that can be written on and erased multiple times. RW DVDs are ideal for temporary storage or for testing videos or discs before committing to a write-once R disc.
In terms of compatibility, DVD-Video players are designed to play DVD-ROM (R) discs, but most models can also read DVD+R. However, there might be some differences in playability between the two types of discs, depending on the player or recorder being used. It is recommended to try a small volume of discs first to determine which type of disc works best with your specific player or recorder.
