CD-RW : Computer Hardware Buyers’ Glossary

The CurrCon Java Applet displays prices on this web page converted with today’s exchange rates into your local international currency, e.g. Euros, US dollars, Canadian dollars, British Pounds, Indian Rupees… CurrCon requires an up-to-date browser and Java version 1.7 or later, preferably 1.8.0_11. If you can’t see the prices in your local currency, Troubleshoot. Use Chrome for best results.

CD-RW (Compact Disc Re-Writeable). CD-ROM (Compact Disc — Read Only Memory) drive that lets you create your own CD (Compact Disk) s, or copy existing ones, computer or audio. The blanks can be erased and cost about $2.10 CAD 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.



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