A rozřešení z Wikipedie:

Many slot-loading CD drives are generally incompatible, (the iMac of 1999 is an exception), but adapters are available into which one can snap an 80 mm round miniCD in order to extend the width to match that of a 120 mm CD, and thus work in many slot-loading devices. There are no adapters for business-card sized CDs
