Mini CDs

I'm sorry if this is already addressed but I've searched to no avail. Is there an adaptor for the mac that will allow me to burn onto a mini cd? The hockey rink shaped ones that people use with products like a business card. I know with a pc you just put it in the tray that slides out. However with the DVD/CD drive being built in on a mac, I'm assuming I need some sort of adaptor. Any suggestions? Thanks in advance.
