What is a Data CD
A Data CD (Data Compact Disk) is a compact disk which is used to store computer data. It stores the data electronically, such as the files and applications that reside on the computer’s hard drive. The data is written on the CD in a continuous spiral running from the center of the CD to its outside rim. All the bits in a file are written one after the other from beginning to end, and then the next file is written, and so on. Data CD is also known as CD ROM.
Uses for Data CD include archiving data, backing up a hard drive or other media or just saving some data or files on the data cd which are not frequently used and hence freeing up the computers space too, creating a test copy of a CD, and sharing information as it can easily be taken from one place to another. An mp3 CD is a type of data CD only. So a data cd could be a cd of mp3s, document, video clips and pictures etc… Data discs may be created using CD-R or CD-RW (Re Writable) media.
The order of the files and folders in a CD layout can be changed at any time before the creation of the CD. For example, the user can move a folder that appears at the end of the Data CD Layout window to the top of the list but changing the order of the files and folders in the CD layout affects only their physical position on the CD. Moving files and folders in the CD layout does not change their original location on the computer.
There have been a lot of enhancements in the quality of the CD:
Cd’s are now coming with boosted recording sensitivity characteristics. The Cd’s are having greater hardness and higher reflectance, for enhanced readout reliability. Also ensures greater protection for recording layer.
The process of writing contents into the Data CD is termed as burning of the data disk. During burning, the files are copied to the disc just as they are, without conversion or modification. After the process is completed, the Data CD can now be used anywhere i.e. can be used in any computer which is having a CD reader attached to it.
