摘要： A video disc player having an adaptive bumper apparatus which tracks the signal pickup stylus to maintain a fixed spatial relation therebetween. The bumper is fixed to an electromechanical transducer secured to the stylus arm support carriage. Signals correlated to the relative disc-stylus velocity having frequency components of the once around rate of the disc are adapted to energize the transducer to cause the bumper to follow the motion of the stylus in the radial dimension. Disturbing visual effects resulting from disc defects, etc. which tend to kick the signal pickup stylus fore or aft of the current track position are significantly reduced.

摘要： A video disc playback system includes a circuit for detecting degradation in signals recovered from a disc and generates a control pulse responsive to the detected degradation. The degradations are of a predetermined duration and represent a predetermined percentage decrease in amplitude. A peak detecting and following circuit is connected for receiving signals recovered from the disc record. The decay rate of the peak detecting circuit is arranged to be substantially equal to a certain minimum duration of amplitude degradations that should occur before it is desired to generate the control pulse. The output signal from the detector circuit is proportioned by a divider circuit and then integrated to produce a signal which is proportional to the average of the detected signal over a relatively long period of time. The proportioned signal is applied to the reference signal terminal of a comparator circuit and the detected signal is applied to the signal input terminal of the comparator. The comparator is conditioned to change states when the detected signal falls below the proportioned signal.

摘要： In a pickup arm drive device of a record player capable of automatically selecting a desired music on a record disc on which a plurality of pieces of music are recorded, at least two inter-music sensors are arranged near a stylus on the pick-up arm to detect inter-music spaces on the record disc. The outputs of the sensors are subjected to processing and by using the resultant processed outputs, the driving of the pickup arm is switched from "lead-in" or "return" operation to an inter-music position servo operation. Therefore, the stylus of the pickup arm can be lowered exactly onto the inter-music space on the record disc even if the record has an eccentricity or warp.

摘要： An anti-skating and/or arm-moving device for a disc-record player comprises two permanent-magnet plates carried by the pickup-arm support and each extending over a sector of a circle round the same, the plates being magnetized, each across its thickness, with opposite polarities to produce each a magnetic flux at right angles to the direction of plate movement, and a coil fixed to the player structure in which two conductor elements extend across the flux of each magnet plate respectively, transversely to the direction of magnet movement, and carry the coil current in opposite directions.Current cut-off means are preferably provided for cutting off the anti-bias current in the winding when, particularly during a manual cueing operation, the pickup stylus is lifted from the record surface, and conversely preventing the application of arm-moving current when the stylus rests on a record.

摘要： A video disc player having a signal pickup stylus for engaging a disc record is equipped with a steering device to provide three degrees of motion to the stylus. The stylus is secured to a stylus arm, the second end of which is compliantly mounted to a support structure. A permanent magnet in the shape of a cruciform with a like magnetic pole at each extremity is secured to the second end of the stylus. Magnetic field producing electric coils are arranged proximate each of the extremities of the cruciform and secured to the support structure so that energization of the coils will apply force to the cruciform causing the stylus arm to pivot about its compliant mounting.
