CDR means compact disc-recordable. Like most compact discs, CDRs can only store somewhere between 700-800MB of data. The unique thing about them is that they can only be used for recording once. After that, it is a read-only disc. As such, whatever you will record on a CDR will remain unchanged forever.
Difference Between DVD-R and CD-R. DVD-R and CD-R are two devices used to store data. While DVD-R stands for Digital Versatile Discs-Recordable, CD-R stands for Compact Disc-Recordable. The basic difference between the two lies in the amount of data they can store. While a CD is able to store only 700 MB data, a DVD-R can hold up to 4.7 GB of data.
