...and in broadcast applications in radio stations, to make start-up times even faster for broadcasters, and thus near-instantaneous! Start-up speed there is critical.

The huge motor/lightweight platter concept is also applied with great success on EMTs. I guess that there was something in it after all (with idlers and D/Ds, that is)...
