发明名称 Video disc stylus suspension apparatus
摘要 A system for suspending a video disc signal pickup stylus arm incorporated with a permanent magnet which is part of a motive means for providing stylus-disc velocity corrections. The permanent magnet is constraind in a flexible "H" shaped suspension to maintain the magnet in a fixed orientation while undergoing translation. The stylus arm is compliantly coupled to the "H" shaped suspension colinear with the magnet. Off axis forces on the magnet are precluded from imparting off axis forces to the stylus arm, thereby eliminating the stimuli which create mechanical resonances in the stylus arm.
