摘要： A stylus suitable for use with a video disc player of a type in which signals representing changes in electrostatic capacity with respect to a video disc are detected, including a scanning surface brought into contact with the video disc for scanning same, a plurality of inclined surfaces, and a plurality of ridges formed by the inclined surfaces. At least one of several meeting points of the plurality of ridges located in a direction in which scanning is performed is chamfered to render the point blunt. A stylus of the aforesaid shape is produced by a grinding method consisting in using a grinder pan composed of a plate of soft resin having a coat of hard material applied to its surface and forcing a forward end of a stylus against such grinding pan.

摘要： A capacitive information disc playback stylus comprising a dielectric support element having in one portion a conical body terminating in a constricted tip. The tip comprises a curved prow surface, a flat electrode surface remote from the prow, shoulders joining the constricted tip to the conical body, and side surfaces which join the prow and the flat surface. The side surfaces, the flat surface, and the prow surface define the edges of a disc-engaging surface.

摘要： A method is provided for forming a pick-up stylus having a record engaging edge located at a predetermined angle with respect to an electrically conductive surface. Two identical jewel elements each having a flat surface, joined together along their flat surfaces. The forward end of the joined work product is ground to a conical tip and the work product is then separated into the two elements each now having a semi-conical tip. A pair of flats are gound on each tip on opposite sides of the semi-cone apex. The flats extend from the previously joined flat surface and intersect each other along an edge which defines the predetermined angle with the previously joined flat surface.

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： One end of a support structure of dielectric material tapers to a tip which has a curved bottom surface. A cermet film composed of a conductive material and a dielectric material which adheres well to the support structure is on a portion of the support structure's surface. The concentration of the constituent materials in the cermet film varies through its thickness. The cermet film at the interface with the support structure has a high concentration of dielectric material while the portion of cermet film at its exposed surface has a high conductive material concentration.

摘要： A bimorph element is interposed between a supporting structure of a video disc player and a support member. A replaceable pickup arm unit carrying a signal pickup which is subject to engagement with a spirally grooved video disc record is releasably secured to the support member. The bimorph element selectively deflects the support member in a manner that displaces the groove-riding signal pickup radially of the disc record.
