    摘要： A multi-function phonograph tone arm control system for a low-friction air bearing supported linear-travelling tone arm system is disclosed. Positive horizontal linear positioning is accomplished by means of an electromagnetic force producing system in which opposing linear forces may be balanced at any point along the path of straight-line travel of the tone arm to position the tone at any desired location. A separate electromagnetic force producing system is utilized to control the vertical pivoting of the tone arm including the pressure of the stylus on a phonograph record. A further motion damping means is provided to stabilize the motion of the tone arm and prevent any unwanted vibration of the tone arm. A means for automatically shutting off the system at the end of a record is also provided.

    摘要： Coupling of pickup arm housing to a slow moving belt for translational motion during record playback is controlled by a play solenoid, while coupling to a fast moving belt for fast forward and reverse motions is controlled by respective forward and reverse solenoids. Player includes manually actuated push button controls for play, forward search, reverse search, pause, reject and power on/off functions. Mechanism actuated switches include a land switch actuated when pickup location is over beginning of recorded information, a travel limit switch actuated when pickup location is beyond ending of recorded information, and a rest switch placed in one switching condition when housing returns to an off-record rest position.

    摘要： 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.

    摘要： There is disclosed a tonearm linear-drive apparatus wherein the pivotal point of the tonearm is moved in the linear direction which is parallel with the pickup stylus linearly moving direction across the record disc being played, by using at least a portion of gravity force. A sliding mechanism having the tonearm supported at the pivot point is provided adapted to slide along a linear track by the portion of gravity force in the same direction as that of the linear movement of the pivotal point of the tonearm. A braking mechanism is provided responsive to the above stylus movement and the above pivotal point movement for starting and stopping the above sliding mechanism movement.
