Once CD's have data put on them, it cannot be erased. On rewritable CD's, the reflective layer on the bottom of the disc is a different compound that, when hit by the CD drive's laser at increased power, will melt, erasing data so something else can be written in its place.

CD-R disks are NOT re-writable. Look for disks labeled CD-RW.
Data can be copied to CDs (Compact Discs) which are writable/rewritable and need a CD/DVD burner to write data. The difference between a floppy and CD is that floppy is a magnetics media and CD an optical media (read/write happens with help of a laser light). - Neeraj Sharma
