How does that work? The disk media must fit around that male cone. Is the
complete disk carried by the clamp arm or something? I need to find one
of these drives to examine.

Seems like an odd way to do it. The metal cone is not going to change in
diameter. So the hole in the media has to just fit it, if too tight the media
will be distorted, if too loose it won't centre.
