摘要： A stylus for tracking stereophonic and quadrophonic sound grooves in gramophone records is designed to resemble a cutting tool, but is provided with tracking or contact edges in lieu of cutting edges, the tracking edges being of a much longer radius of curvature than comparable cutting edges. A tip (1, 11, 21, 31) of the stylus (2, 12, 22, 32) has at least one substantially flat surface (5, 15, 29, 39) forming a leading front side of the stylus during tracking and has an isosceles triangular, trapezoidal or circular segment-shaped section bounded by tracking edges (6, 7; 16, 17; 26, 27; 36, 37) having a relatively long radius of 3 to 8 .mu.m.

摘要： A retainer for holding the stylus arm of a video disc signal pickup cartridge is described which is low cost and occupies little space in the cartridge. The retainer is formed from flat spring stock and shaped to have a three-sided body with fingers extending from the parallel sides to encompass and hold the stylus arm. The retainer is inserted through a top wall of the cartridge and spring tabs which are formed in the sides of the retainer body engage opposite surfaces of the top wall to secure the retainer thereto.

摘要： 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.

摘要： A head shell for a record player tonearm comprises a composite material essentially consisting of a thermoplastic resin and graphite powder. The composite material is prepared by kneading the components, rolled to impart a degree of orientation to the graphite powder particles, which are in the form of flaky graphite and then molded into a shell, along the surface of which the graphite particles are oriented. Head shells wherein the composite material is oxidized at the surface and head shells wherein the composite material is carbonized or graphitized are also included. A light weight, rigid head shell having a high specific modulus of elasticity is obtained through a simple procedure at low cost.

摘要： In a signal pick-up apparatus for reproducing a recording disc, a pick-up cartridge casing is detachably loaded at a predetermined position on a pick-up apparatus structure. An arm is rotatably supported at one end thereof, within the casing. At its other end, the pick-up arm has a reproducing stylus which contacts the recording disc, an elastic member for supporting the pick-up arm with respect to said arm support member, and a member for urging the arm support member in a direction which accommodates the pick-up arm within said casing. The other end of the arm support member is depressed, within a direction for causing the reproducing stylus to contact the recording disc and further causing the elastic member to deform after a contact between of the reproducing stylus and the recording disc.
