What does CDRW (CD-RW) mean?
Compact Disc WRite multiple times. A CDRW (CD-RW) starts off absolutely blank. Data is then written to the media. This writing process is often called ‘burning’ a disc. A blank CD-RW can have data written to it multiple times. This format is good for archiving type uses where the data is not going to be shared or copied for use by other computers.
