Using micro cd's in a MacBook Pro Is there a proper way to insert micro cd's so they are less likely to get stuck inside the cd slot on my MacBook pro?
Your MacBook Pro User Guide will state the following:

Slot-loading SuperDrive
This optical drive reads and writes standard-size CDs and DVDs.


By standard-size CDs and DVDs it means that the slot-loading drive is not designed to take mini/micro optical discs of any sort.

Instead, you will need an external tray-loading optical drive or access to an older Mac with one. Of course, if it's some sort of promotional material, software, etc, then you may be able to view/download it from the internet.
