This is an interesting short discussion regarding how floating disc brakes differ from solid disc brakes and why a semi-floating disc is better than full-floating discs for street riding:

Another mysterious bit of nomenclature explained. Thanks Richard.

It looks like my '13 F800GT has a semi-floating setup in contrast to my '94 R1100RS (which has full-floating rotors). Quite an interesting development of braking design over the years. Both have great stopping power.
