I bought one of those 100 packs of Office Depot CDs. First time I've used them.
I burned some music to one of them on my home PC--with the slide out drawer type CD drive.
I took it to work and inserted it into an older iMac--with the slot type CD drive.
When I ejected it from the iMac it didn't want to come out. It tried to eject it and the very edge of the disk was visible momentarily. I was finally able to grab it with a thin metal ruler with a piece of tape stuck to it.
Other CDs eject properly and they all seem to be the same thickness.
Any idea what's going on here?
