Windows doesn't force you to use fullsize CDs like Apple does.
In fact Windows doesn't care whether your drive supports small CDs or not. Come to think, I don't think Mac OS cares either, it's Apple's choice of stylish rather than functional hardware that causes your problem.
There are (or used to be) slotloading drives for PCs as well which had the same problem. Haven't seen any in years though, maybe Apple bought them all to make sure of having a supply for the next decade
I seem to remember there being plastic thingies you could put a small CD in which would fool the drive into thinking you were loading a regular size CD with just the inner part filled with data.
Maybe those still exist.
