ABSTRACT:
A cutting stylus assembly for electromechanically recording short wavelength video signal information in a metal master is supported in a cutterhead suspension apparatus. In the suspension head apparatus the cutting stylus assembly is supported by an air puck device so that the stylus cuts an information track having a given quiescent depth. Two sets of parallel spring steel suspension members are used to mount the cutting stylus assembly and air puck to an electromechanical recording lathe. These suspension members are used to control the cutting stylus assembly and air puck motion, to maintain a fixed stylus assembly to air puck plane relationship and to effect a variable preload for the cutting stylus system.
