Blank compact disc recordables, or CD-Rs, are electronic storage devices that do not contain any data. Data can be stored on these CD-Rs through a process called ‘CD burning’. A blank CD-R, a computer, a CD writer, and appropriate computer software are required to transfer data onto a blank CD-R. Data stored on the CD can be accessed or viewed any time, on a computer.
In any business or government organization, vital information needs to be stored somewhere as backup. Large quantities of data can be stored on blank CD-Rs and kept somewhere safe for future use. Apart from this, it can also be used to store movie files, mp3 audio files and digital images for personal use.
A blank CD-R is a relatively cheap way of storing voluminous amounts of data. The CDs cost less than 50 cents apiece if bought in bulk. A single CD can store around 700 MB of data, which is approximately 80 minutes of stored digital video files. While performing data backup, it is important to move all the required files and folders to a single folder. Furthermore, these should be classified according to different data types, such as documents, pictures, spreadsheets and video files. This will avoid confusion and save time.
After data is transferred to a CD, it needs to be stored in a safe place away from heat, excess moisture, magnetic fields and dust particles. These conditions can easily destroy or corrupt the data stored in the CD. Usage instructions given by the seller should be followed properly.
One negative aspect is that these CDs are increasingly being used for selling copyrighted material. This results in piracy and can result in huge losses to companies. Blank CD-Rs are certainly the most cheap, fast, and portable medium of storing data.
