ABSTRACT:
A stylus assembly for damping impulsive radial motion of the stylus during playback of a grooved video disc record. Included in the stylus assembly is a moment arm perpendicularly attached at the free end of the stylus arm and parallel to the disc record when the stylus is engaged for playback. A mass is mounted to the moment arm to contribute increased inertia to lateral motion of the stylus only in a direction radially across the record. The mass is designed to permit tracking a record groove in the presence of groove eccentricity but to resist motion due to impulsive forces imparted by record defects or particulate matter thereon.
