The result is that the created CD media will play in regular CD players as if it were a regular CD, in most cases. Since the media is being physically altered by a process of heat and chemistry, the change is permanent and irreversible. Once any part of the CD has been written, the data is there forever. Some drives allow you to record some information in one sitting, and then more information later on, if the disk is not yet full. CD-R media are generally 74 minutes in length.
Some media seems to work better than others in some drives.
I personally think they are not an appropriate avenue for backup, given their write-once nature. This page has been served 13946 times. Copyright 1997-2001 Charles M. Kozierok . All Rights Reserved. Not responsible for any loss resulting from the use of this site .
