why do me blank cd's keep being ejected

[1966stupot]

hello, we have a macbook osx 10.5.8, when i insert a new, blank cd it keeps being ejected. I have bought a new bundle of blank discs and they still keep being ejected - can anyone help or do i have to take it to an Apple store....

Many thanks and Happy new year.

What brand?
Type, -R, +R, +RW, etc.?
CD or DVD?

CD's and they're single use - used them for years and suddenly they're being (r)ejected.

What happens with software installation discs like the Mac OS Install DVD, Office or iWork if you have them? How about music CDs? If nothing reads or mounts on the system you could be facing an issue with the drive. If a particular type of media reads but others do not you may wish to consider resetting the SMC.
