How to unlock a CD

When I try to copy a file from a previously written CD I am prevented and Get Info won't let me "unlock" it (or the CD). The lock icon at the bottom is greyed out. I've turned on File Sharing in system Extensions and set Share on Get Info but to no avail. What can I do?

Thanks for your reply.
No, I'm not trying to write again (it's full and not appendable anyway), I'm just trying to copy the files on the CD onto my desktop or some other area in my hard drive. When I drag a file off the CD the cursor turns into a circle with a diagonal line through it like a no entry sign and when I "let go" the file springs back to the CD.
