David, Mini CDs do not have to be round. They only have to fit in the inner most resess of the CD drive bay. Since the data only takes up the middle and outwards they can stop before the shape hinders this. They did have problems with producing business card cds as they were not good at spinning around and made noises and were not reliable since they were jumping around the bay so much. After a while i guess they found a nice shape that could spin at high speeds. I have seen CDs of all shapes some of cars some of the sun with spikes out of it. Some CDs plain and simply will only work well on like laptop type cd bays where you place the cd on a pin etc. This is all based on stuff a supplier told me when i was in Singapore just before the business cards were mainstream.
