What is the Difference Between DVD-R and DVD+R?

DVD-R and DVD+R are two competing standards for recording data on DVDs. The major difference between them is the way they handle recording and the hardware required for recording. Here are the key points:

• Recording method: DVD+R discs must be recorded by a +R drive or video recorder, and DVD-R discs must be recorded by a -R drive or video recorder.
• Compatibility: DVD-R has greater compatibility with older DVD players (pre-2004), while DVD+R is more compatible with newer players.
• Error handling: DVD+R is more resilient to errors and can handle more scratches compared to DVD-R.
• Industry support: DVD-R was developed by Pioneer and is supported by the DVD Forum, which includes Mitsubishi, Sony, Hitachi, and Time Warner. DVD+R was developed by the DVD+RW Alliance, which includes Sony, Yamaha, Philips, Dell, and JP.

Despite these differences, both DVD-R and DVD+R share some similarities:

• Write-once formats: Both are write-once formats, meaning data can only be written to them once.
• Capacity: Both have single-sided capacities of 4.7GB.
• Finalization: Both require finalization after recording for broad playback.
• Data storage and video applications: Both can be used for data storage and video applications.

In summary, the main difference between DVD-R and DVD+R lies in the recording method and compatibility with different DVD players and recorders. However, both formats share similarities in terms of capacity, write-once nature, and their use for data storage and video applications.
