difference between cd and dvd
Talking of differences, the data in a DVD is advanced in quality and sharpness and video files in DVDâs are of HD quality, and if you wish to store films, it is better to use a DVD-R instead of a CD-R as not only is the video quality better, more space means you can store up to 5 films in a DVD-R, while a CD-R can hold only one film.
Thatâs why CD-ROMs top out at about 650-700 MB of data, while DVDs can hold multiple gigabytes of data. Since the pits are more tightly written on a DVD disc, the mechanism in the drive for reading them also has to be finer and more precise. Thatâs the main reason that DVD drives cost more than CD-ROM drives. DVD drives can also read regular CD-ROM discs with no problem, since the difference is mostly in the spacing.
