    Abstract: RCA 74,684 Flylead for a Video Disc Pickup Stylus 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.

    Abstract: RCA 74,107 An adaptive video disc record stylus kicker system for inducing limited stylus translation radially across the disc record. Control circuitry responsive to track identification signals recorded on the disc and to player commands evaluates the error between actual kicker induced stylus translations and the programmed kicker induced stylus translations to calibrate the stylus kicker drive signals.

    Abstract: A DISC RECORD LOCKED GROOVE SKIPPER In a system for playing back prerecorded signals from a spirally-grooved disc record by a groove-engaging signal pickup secured to a pickup arm when relative speed is established therebetween, a locked groove escape apparatus is provided. A transducer varies the position of the signal pickup in relation to the groove in a manner that opposes deviations of the relative speed from a predetermined speed. A carriage housing the pickup arm is mounted on the player base for movement between a playback mode and a standby mode. The carriage is driven radially inward in synchronization with rotation of the disc record during playback independent of radial motion of the signal pickup due to the spiral groove. A locked groove detector coupled to the transducer generates a locked groove recognition pulse when the signal pickup encounters a locked groove. A guide member is secured to the carriage contiguous to the free end of the pickup arm such that when the transducer drives the pickup arm in response to the locked groove recognition pulse against the guide member, a radially inward movement of the pickup arm is effected, whereby the signal pickup is relieved from the locked groove condition. In another embodiment of the present invention, a steering member is secured to the carriage adjacent the pickup arm such that the steering member and the disc record center are on the opposite sides of the pickup arm. When the signal pickup encounters a locked groove, the advancing steering member engages the pickup arm in order to effect radially inward movement thereof, thereby relieving the signal pickup from the locked groove condition.
