What Does CD Burner Mean?
A CD burner is a device that records information onto compact discs. It typically takes the form of a rectangular metal (or metal/plastic hybrid) enclosure with a slot or tray into which compact discs are inserted. A laser inside the enclosure burns digital information onto the disc, which can in turn be read on standard CD-reading and playback devices.
Techopedia Explains CD Burner
Compact discs store and transmit binary data through sequences of bumps that spiral from their center. CD burners etch information onto CD-R or CD-RW media, which are sold as “blank” formats onto which information can be stored on a permanent or (in the case of CD-RW) temporary basis. Like prerecorded CDs, the blank discs are made up of thin metal and polycarbonate layers. Between those layers is a polymer dye that is transformed by the burner’s laser impressions.
