what is the difference between DVD-R & DVD+R/DVD-RW&DVD+RW?

Answer 1

DVD + R/RW will only play and record on + R/RW Drives

whereas DVD - R/RW will only play on and record on - R/RW Drives, (However these need to be finalised first).

basically the discs all do the same but on different compatible
DVD Recorders .

I own a dvd +R/RW recorder :)

I hope this helps you

Answer 2

A DVD/R can only be recorded on once.
A DVD/RW can be erased and recorded over an unlimited number of times. (the "RW" stands for rewriteable)

Answer 3

dvd-r anddvd+r are different formats no real difference
dvd-rw means you can record on it and then wipe info off and use for somthing els.
you can get rw in cd,s and dvd,s

Answer 4

I wondered this a few years ago also, and it was explained to me that "R" means you can only record on them once, then the disk is finalized and can't be used to record any other data on.

The "RW" can be "re-written" more then once. You can erase any data from these disks and re-use them.

(this is probably an extremely over-simple explanation, but that's how it was explained to me and all I really needed to know for my purposes at the time.)

Answer 5

derrick L is talking bo11ux

- or + indicates the method the drive uses to write the data - was the first variant, + was slightly faster. virtually all DVD players can read + or - disks once they have been finalised and made palyabel in a standard player.

-R or +R means its a write once disc.. ie youcan only wrtie to the disk once, it can be read many times

RW means the disk is rewritable...... ie you can overwrite the stuff on the disk. the disk can be reformatted and used again. with a R disk you jhave but one chance to write on the sik (you may be able to perform that writing over several sessions but you will only be able to write to the disk once.

its a bit confusing... but some disks support session writing where it writes a parcel of data to the disk, you cna then write subsequenmt parcels of data at other times, but this will be added to the back of the exisitng block of data.

Answer 6

R means you can record and not write over; RW you can record and write over the recording.

Answer 7

Simple if it only has R it only means you can view or play a DVD - If it has a W it means you can record as well.

Answer 8

DVD+R
DVD+Recordable defines a standard for recordable DVD drives and media defined by the DVDRW Alliance.

The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD Forum DVD-R specification. DVDRhelp DVDR information



DVD+R DL, DVD+R9
DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 7.95 GB or around 8 540 000 000 bytes (called DVD-9) and a double sided dual layered disc 15.9 GB or around 17 080 000 000 bytes (called DVD-18).

DVD-Audio can only be played on DVD Players with DVD-Audio support (most DVD Players do not support this format). DVD-Audio is currently competing with SACD as the new audio defacto standard.

DVD-VR
The format is known as "DVD dash VR" or DVD-VR. Its actually known from the DVD specification as DVD-RTRW for real-time read/write. One thing that makes it different from the "DVD Video" standard which is used by professionally repliacted DVD's is that the indexing for DVD-VR is forward only. This allows the "writing" of the disc image immediately without having to come up with some cludge to try to write a fully index'd DVD Video file. Burnworld DVD-VR Info



DVD±R
A term used to cover both the DVD-R and DVD+R standards in one word.



DVI
DVI stands for (D)igital (V)ideo (I)nterface. DVI is a new form of video interface technology made to maximize the quality of flat panel LCD monitors and high- end video graphics cards. It is a replacement for the P&D Plug & Display standard, and a step up from the digital-only DFP format for older flat panels. DVI is becoming increasingly popular with video card manufacturers, and most cards purchased include both a VGA and a DVI output port.
In addition to being used as the new computer interface, DVI is also coming out as the digital transfer method of choice for HDTV, EDTV, Plasma Display, and other ultra-high-end video displays for TV, movies, and DVDs. Likewise, even a few of the top-end DVD players are now featuring DVI outputs in addition to the high-quality analog Component Video. Don't expect to throw away all your old video cables just yet, but keep an eye out for DVI availability in the future.
