The good news is that the new CDs have exactly 12 cm and the miny format is described on the boxes and on the shelves as 8 cm CD-R or RW. The customers seem to have no qualms about understanding this designation.
I am sure that the new DVD-RW will also come in 8 cm format. This format is a lot more compact and it fits into a pocket. The curent mini CDs have a capacity of only about 200 MiB which is already a far cry from the 1.4 MiB but if they come in DVD-R format this capacity should increase considerably.
