  • Damping mechanism for a video disc stylus holder
    Patent number: 4441176
    Abstract: Video disc stylus holders are designed to provide vertical decoupling of the pickup stylus from the stylus support arm. The compliance designed into the holder gives rise to mechanical resonant modes which affect the recovered signal in the audio range. A rigid damping element secured to the compliant section of the stylus holder by a lossy adhesive or a lossy mass rigidly secured to the compliant section of the stylus holder reduces the amplitude of the resonant modes.
