Difference Between DVD-R and CD-R
DVD-R and CD-R are two devices used to store data. While the DVD-R is Digital Versatile Discs-Recordable, CD-R is Compact Disc-Recordable. The fundamental difference between the two lies in the amount of data they can store. While a CD is able to retain 700 Megabytes, a DVD-R can hold up to 4.7 gigabytes of data. Both can be used to store audio and video. In DVD-R you get 120 minutes of video, while in a CD-R get about 80 minutes of audio. To support your data, the DVD-R is preferred because of its larger capacity and it is economic as well.
DVD’s and CD’s are blank when you buy them and you can fill your own data on them. Speaking of differences, the data in a DVDs have better quality and sharpness and videos in DVD are HD. For saving movies DVD-R is better because it can hold more than one film while CD-r can hold only one film because of its limited storage capacity.
To burn a DVD-R, you require a DVD burner which is the software to burn audio files or videos on your DVD-R. The DVD burner also has the ability to burn a CD. The advantage between the two is visible when you try to watch a DVD or CD on your DVD player. It is very much possible as a DVD player that can read both CD DVD but a CD player can not play a DVD.
Earlier, there was a huge price difference between DVD-R and CD-R. But with the advancement of technology, the costs have become almost similar. The CD is still a little cheaper than the DVD and it is probably the only advantage they have over DVD.
Today there are rewritable DVD-RW and CD-RW are easily available which means you can record and then erase the data and use them again and again to store new data though they have a limited life and you cannot keep re-writing on them for very long period.
