Cartridge force and bias adjustment gage

摘要

An apparatus for aiding in the final orientation of a video disc stylus assembly within the stylus cartridge. A fixture is arranged for receiving and securing cartridge assemblies in precise spatial relation to successive assemblies. A cantilever secured in fixed spatial relation to the cartridge has its free distal end arranged to engage the stylus assembly, which engagement produces deflections in the cantilever relative to the position of the stylus assembly with respect to the cartridge. Electro-mechanical transducers, coupled to the cantilever, measure and indicate minute deflections therein. The stylus position is then altered manually or by controlled mechanical means in accordance with the measured deflection in the cantilevers.
