Let me add that "Arm" does not mean a tone arm or support that the 
recording head would be mounted on.  There is a rod that is attached to 
the armature of the cutting stylus, and this is encased in rubber.  The 
rod and rubber line is about six inches long and sticks out from the 
side of the recording head.

And I agree that Nick is the real expert.
