ABSTRACT:
A flylead for providing electrical connection to a video disc signal pickup stylus, and exhibiting a prescribed force directed toward the record disc as well as a prescribed compliance to lateral translation. A substantially flat metal flylead element is configured with a respective narrowed region proximate each of its ends to permit the section between the narrowed sections to twist independent of the ends when mounted. The flylead, in its normal play configuration, is elastically deformed in an arc with the narrowed regions outside the region of the arc. A lateral translation of one end of the flylead induces a twisting in the arced portion of the flylead, which twisting relieves the flyleads resistance to such translation.
