the difference between +r and -r

I forget, just google it, I did that awhile back. One was better I think if you did movie editing or something.

They are simply different writing formats. Most drives today support both formats. There is more information here: http://en.wikipedia.org/wiki/DVD_formats

You can looked it up but I use +because that is what works with my equipment. You need to know which will work for you.

They are fundamentally the same, but R stands for retail. It has a few less features and a shorter warranty. Go for the version without the "R and you will get a 5 year warranty and some more useful control features. I bought 2 of this one, but Amazon has it direct for a little less, but they charge tax in CA. http://www.amazon.com/gp/aag/main/ref=olp_merch_name_9?ie=UTF8&asin;=B00G4CIG7M&isAmazonFulfilled;=1&seller;=A2CHZ585KZGNN0

When DVD media technology was first developed, the plus (+) and dash (-) formats had different writing/reading specifications. Today, most DVD writers and readers work with no noticeable performance differences between DVD+R and DVD-R disc formats. Check with your manufacturer's suggested DVD format to ensure compatibility - especially with older units. (From Verbatim Website...)

There are 2 nozzles. I'm not familiar with the R designation. One nozzle is a round one, the other has a flat opening and sprays in a flat fan type stream. I hope that answers your question.

These are two different formats used by DVD recorders. The -R is the most common. Some recorders handle both formats but some can only record to one of them. You should check the instructions for your specific recorder to see which format(s) it can use.

I'm having difficulty recalling as I use mine only at 0 deg. --- but it seems as if the choices were indeed only 0 and 90. EDIT: based upon consensus, I'm guessing that my previous comment is not correct!

I'm not sure what the + version is. This is the version they have had for years. Tried and true!

If referring to DVD -R; DVD+R, I do know that it does record on +R, haven't tried -R. I did all my recording on +RW

A positive should either be a + or =. I'm not sure what the heart shaped window test is, so I could be wrong.

Hi there, DVD-R stands for Recordable. DVD+R stands for Rewritable. +R = you can use again but they cost more. I'm sorry but I have not tried that feature on these.

I'm sorry, I don't know the difference between the two. I wish I was more helpful with this question.

They are on separate keys actually.The plus minus on the per cent key means you can use it to add or subtract a per cent. So, for example, 300 minus 5 per cent = 285Give it a try

The R value varies per application. The more air space there is results in higher efficiency, so, if used in a typical installation such as stapled to rafters or across joists where there is at least several inches of air space it will have a much higher r-value than if it's mounted directly to a surface, for example, as a wrap for ductwork. The product description states: "Has R 16.8 value for crawl space applications and R 6.13 value for basement walls." Those are much higher r-values than I've seen before through testing (more than double), though may represent the max value that can be achieved if installed with a very large air space for those type of applications.

I have never had any reason to look at either of those numbers. I guess I would contact the manufacturer & pose the question there. Or, you could use the old method of trying both types and see if you can find any "difference" (that's my method of solving a question...)" :) :)
