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.

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
