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.
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.
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.
