How many times can you write to a CD-R?
Because of this high reflectivity, CD-R discs can be read or played back in most CD players and CD-ROM drives. Compact Disc Rewriteable (CD-RW) is a fully rewriteable media, meaning that any spot on a CD-RW disc can be rewritten up to 1,000 times (based on the current standard).
How do I know if my CD is rewritable?
To summarize, look for discs ending in “-R” if you want single-use recordable CDs or DVDs. Look for “-RW” if you want discs that you can use more than once.
How do I erase a non rewritable CD?
To erase a nonrewritable CD, you must destroy the disk and render the data unreadable. Do this by cutting, shredding or scratching the surface of the disk to the point where it cannot be read; or destroy old CDs containing financial or other sensitive information to protect yourself against identity theft.
Can you cut CDs with scissors?
( Any sharp scissors will probably work.) When the CD is the right temperature, the scissors will easily cut it. If the CD is too cool when you are cutting it, the cut edge can become curled or dented, so take your time with this step, and be careful as you cut.
