A Digital Versatile Disc (DVD) uses new optical storage technology to hold more data than a Compact Disc (CD).
- A DVD reader uses a different laser wavelength than a CD reader.
- A DVD have small pits in it to hold more data. Smaller pits means more can be burnt into the disc.

∙ 15y agoDVDs are designed to be read from a narrower beam of laser light than CDs so this allows more information to be stored in the same amount of space. There are also more efficient formatting methods that help as well.

Why is a DVD more preferrable than a CD?
A DVD is more preferable than CD for its higher storage capacity than CD. Generally, a CD can hold up to 700 MB whereas a DVD can hold up to 4.7 GB. DVD is not only superior than CD in storage capacity, but also it is superior in requirement. It has been experienced that some system softwares require more than one CD or even one complete movie requires two or three CDs for storage. The use of DVD can overcome these problems as one DVD can be used to store the information of a number of CDs. A DVD requires a DVD combo drive or a DVD player which allows to read CDs as well as DVDs. Thus, a DVD is more preferable than a CD.
If a dvd-rom and a cd-rom are the same size how is it possible for a dvd-rom to hold so much more data than a cd-rom?
The DVD has a greater density. The laser can read finer grooves.
Is a CD different than DVD?
CDs and DVDs share the same physical format but the DVD stores more data that a CD. It does this a much finer set of optical tracks on the disc than the CD has. In a similar way, Bluray discs hold far more data than a DVD.
What holds more information than a CD?

How many CD worth of data can a single DVD hold?
A regular 700mb cd will fit about 6.7 CDs onto one regular 4.7GB dvd
How many CD's fit on a DVD?
All of the data on a CD can be recorded on a DVD. DVD s hold much more data than CD s. And as such, all the files may fit on a DVD unless they were compressed on the CD and then some how they become decompressed when they are recorded on the DVD. A CD has data capacity of 700MB. A single layer DVD has a capacity of 4.7GB and a double layer one has capacity of 8.5GB. So data of at least 6 CDs can be copied on a single DVD.
Can a CD hold video data?
any cd can hold video data but it will not be in DVD format, it will be in VCD, MPEG, AVI etc. DVD format, which is VOD, has large file sizes.
