Difference between 'DVD-R' and 'CD-R'


V

Hi:
I got 'DVD-R' this morning, because when I attempted of making 'PC Recovery'
disk, the computer asking whether I choosed 'DVD-R' route or 'CD-R's.'

Because, there needs only 4(four) DVD-Rs while it's needed 16(sixteen) CD-Rs
for 'PC Recovery' of my HP notebook .

Someone told me, however 'DVD-R' uses for 'movie,' not regular back-up
purpose, that has been confusing me a great deal.

My question is;
What 'DVD-R' really using for?
Also, what difference between 'DVD-R' and 'CD-R?'

Thanks for your help.

CD-R = writable CD holding up to 700MB of data or 80 min of uncompressed
audio

DVD-R = writable DVD holding up to 4.7GB of data or 2 hrs of video

DVDs hold a lot more, so your recovery program needs less of them to
store the same amount of information.

Since either one can hold computer data, you can use either to backup
your files. Which to use depends on how much data you have.

The DVD-R discs can be used for either data or video. The more common media is
identified accordingly as 4.7 GB of data or 120 minutes of video. Some are
marketed for video uses due their slow write speed which is normally 4x maximum.

The CD-R discs can be used for either data, audio, or for some limited video
formats such as VCD or SVCD. Some of these discs are marketed for audio use due
to their slow write speed of 1-4x. CD-R media initially was marketed with a
capacity of 650 MB of data or 74 minutes of audio but the more common capacity
found today is 700 MB of data or 80 minutes of audio.

So for backups, the DVD media is a better choice due the economics of its
capacity.

You may also want to consider using DVD-RW media, which is erasable. Some may
disagree with this choice, but I never had a problem with these when used for
any purpose.

What the chance that a device that can handle the dvd-r format cannot handle the
dvd-rw format?

If so, can you cite any current examples?
