CD-RW

CD-RW (Compact Disc Re-Writeable). CD-ROM (Compact Disc — Read Only Memory) drive that lets you create your own CD (Compact Disc) s, or copy existing ones, computer or audio. The blanks can be erased and cost about

each. Last revised/verified: 2007-10-09 Usually the process of writing the reusable blanks is much slower than non-erasableones. UDF (Universal Disk Format) software such as DirectCD lets you treat the CD-RW as a giant floppy, adding to it a bit at a time. Most drives are either pure CD-ROM, or combination of CD-ROM, CD-R (Compact Disc — Recordable) and CD-RW. Speeds are written 8×4×32× meaning 8 times faster than an audio cd plays to write, 4 times faster to rewrite an erasableCD and 32 times faster to read.

Advantages

You save money over the long run.
More environmentally conscious because there is less plastic to discard. With regular CDs (Compact Discs) you can end up with shopping bags full of backups.

Disadvantages

Cost more to purchase.
Slower to write.
When you erase them, sophisticated spies can still read the some of the material that was previously on the disc.
You can’t rewrite the label. It works best if you put a label on to start, the date stamp each update.
You have the extra erase step before use.

Be careful discarding CDs. They may contain passwords, bank accounts, credit card info, identity theft info… A heavy duty shredder will destroy them.
