What is “CD-ReWritable”?
CD-RW is the most recent addition to the compact disc family. Earlier dubbed “CD-Erasable,” the name CD-ReWritable was selected in bringing the product class to market. As the name implies, CD-RW is a media and recording system that allows the user to erase previously recorded information and then to record new information in its place, making short-term storage feasible on CD media. This is accomplished by means of a new CD-RW media using “phase change” technology that allows a recording laser beam to change the media material from amorphic to crystalline by means of a shift in power. The new CD-RW drives include all the functionality of previous CD-R drives, allowing them to create write-once CD-R discs as well as rewritable CD-RW discs. 2. Does CD-RW obsolete CD-R? No. While this new addition to the CD family allows it to serve numerous applications where erasing old information is important, it will continue to generate CD-R discs for information that must not be altered.
