Title: DVD Type +R or -R ???
Post by: Gordon Buck on July 08, 2007, 05:57:34 pm

Any reason to prefer DVD +R or -R for archiving image files?

Any reason to prefer +R or -R when making a video (using Proshow) to be played from a DVD player?

Just be sure the format you choose is compatible with the player you intend to use. My (Dell) PC came with a DVD-R burner, but my Panasonic DVD player hooked up to my TV only reads DVD+R.  

I discovered this when I went to burn a DVD of LLVJ16 DOH!!!    

Replacing the burner with one that does both + and - R is much cheaper than replacing the DVD player, so that's what I'm going to do.

It's mainly only an issue with old equipment.  Pretty much anything the last 2+ years reads and writes both.

DVD+R is preferable for archiving. It is a newer and more robust format than -R.

See Wikipedia:
"There are a number of significant technical differences between the "minus" (actually strictly incorrect - it was a hyphen prior to the introduction of the DVD+RW format) and the "plus" format, though most consumers would not notice the difference. One example is the ADIP (ADdress In Pregrove) system of tracking and speed control being less susceptible to interference and error than the LPP (Land Pre Pit) system used by DVD-R, which makes the ADIP system more accurate at higher speeds. In addition, DVD+R(W) has a more robust error management system than DVD-R(W), allowing for more accurate burning to media independent of the quality of the media. Additional session linking methods are more accurate with DVD+R(W) versus DVD-R(W), resulting in fewer damaged or unusable discs due to buffer under-run and multi-session disks with fewer PI/PO errors."

There are also quality differences between brands of DVDs. Again, there is lots of info on the internet. If you are serious about archiving, select a high-quality brand such as Taiyo Yuden which you may have to order from a speciality supplier.

I use Sony DVD+R.  There are lots of cheap brands out there that do not have good longetivity ratings, but Sony is fairly good.  +R has more robust error correcting information on it, if I remember right, always a good thing for archiving.

Although I once did have a spindle where about 25% of the DVDs on it were unwritable.  Strangely, so did a colleague of mine who purchased his around the same time.  Probably a bad run.

DVD+R for your image files. See this reference [a href=\"http://adterrasperaspera.com/blog/2006/10/30/how-to-choose-cddvd-archival-media/]here[/url]
