There are many different things between the CD and DVD Media, such as what they hold and how much they hold.
Data pits and lasers A disc has microscopic grooves that will move along in a spiral around the disc. CDs and DVDs both have these grooves, with laser breams applied to scan these very grooves.
As you may know, digital information is represented in ones and zeroes. Inside of these discs, very tiny reflective bumps known as lands and non reflective holes known as pits, which can be found beside the grooves, reflect both the ones and the zeroes of digital information.
By reducing the wave length of the laser to 625mm or more infrared light, DVD technology has managed to write in smaller pits when compared to the standard technology of CD. The minimum length allowed for a pit in a single layer DVD-R is .4 micron, which is obviously more than the .0834 micron that a CD offers.
The tracks of a DVD are narrower as well, which allows for more tracks per disc, which also translates into more capacity than a CD. The average single layer DVD holds 4.5 GB of data, while a CD holds a mere 700 MB.
Layers
As stated above, a DVD has smaller pits and the lasers need to focus on them. This is actually achieved by using a thinner plastic substrate than in a CD, which means that the laser needs to pass through a thinner layer, with less depth to reach the pits.
Data access speed
DVDs will access data at a much faster rate than a CD can. The average 32X CD-ROM drive reads data at 4MB a second, while a 1X DVD drive reads at 1.38MB a second. This is even faster than an 8X CD drive.
Universal data format
The recording formats of CDs and DVDs are quite different, as DVDs use UDF, or the Universal Data Format. This format allows data, video, audio, or even a combination of all three to be stored in a single file structure.
