Sometimes you learn about something when you are presented with options. I never knew or better to say, I never figured out that there exists two different formats for a CD/DVD disk. It was last week, when I went on Amazon to buy a DVD pack for myself that I found that there actually exists two different DVD types (excluding others like RW, RAM), DVD-R and DVD+R (DVD minus R and DVD plus R) and it was then that I began reading more on that and finding out what are the differences.
So in case you are still not sure about the key differences between –r and +r formats and why do they even exists, then I am jotting down my findings.
Existence DVD-R vs DVD+R:
DVD or Digital Versatile Disk is a high storage disk that can store data up to 4.7 GB (or higher in different formats) unlike CDs that can usually store data of around 700 MB in size. DVD-R is a recordable format that can be written once but read again and again. Both DVD-R and DVD+R formats are similar when compared to size, and read/write times.
DVD-R was officially approved by the standards group DVD Forum whereas DVD+R was not approved by the DVD Forum standards group, but are instead supported by the DVD+RW Alliance group. Of the two, DVD+R is the more recent one.
Compatibility DVD-R vs DVD+R:
Since DVD-R is the mostly used and older of the two formats, you won’t find any issues in playing DVD-R disks whereas the DVD+R disks can only be played in supported DVD players. In simple terms, a DVD+R player can play both DVD-R and DVD+R disk but DVD-R player can only play DVD-R disk.
So answer to which DVD disk you should buy, depends on which player you have. If yours is a recently bought player, then you should not worry as you should not face any compatibility issues since manufacturing companies keep things like this, in mind.
Functional Difference DVD-R vs DVD+R:
According to the claims of the DVD Alliance, using a DVD+R/+RW recorder will let you do the following:
• Instantly eject without having to wait for finalized formatting while recording.
• Ability to record one DVD disc partially on PC and partially on television.
• While the disc is being formatted, you can simultaneously record on already-formatted portions of the same disc.
• Enhanced ability to edit file names, movie and song titles, and playlists.
Apart from these facts, DVD+R will also require you to shell out more money than their cheaper counterparts DVD-R.
