Abstract
Perfeccionamientos en aparatos saltadores de surco para la reproducción de video disco, del tipo de aparato que se dispone en un sistema para recuperar información previamente grabada en un disco que tiene una pista de información espiral por una aguja seguidora de la pista cunado se establece una velocidad relativa entre la aguja y el disco, donde el funcionamiento normal del sistema comprende detectar la información previamente grabada a lo largo de espiras sucesivas de dicha pista espiral en una progresión regular hacia una extremidad, caracterizados porque comprenden un carro sujeto a movimiento de traslación en correlación con movimiento radial de la aguja, seguidoras de la pista durante la reproducción, teniendo el carro una abertura en su pared inferior, un brazo de aguja portador de la aguja seguidora de la pista sobresalga a través de la abertura cuando el brazo de la aguja desciende durante la reproducción, un imán permanente sujeto al brazo de la aguja cerca de cada uno de sus extremos, un par de boninas separadas, que tienen núcleos magnéticos, para proporcionar un campo magnético sustancialmente uniforme en entre las mismas al activarse; medios para montar el par de bobinas en el carro de modo que el imán permanente sujeto al brazo de la aguja cerca de cada uno de sus extremos, un par de bobinas separadas, que tienen núcleos magnéticos, para proporcionar un campo magnético sustancialmente uniforme entre las mismas al activarse, medios para montar el par de bobinas en el carro de modo que el imán permanente se sitúe entre las mismas, y medios para activar de una forma selectiva las bobinas y producir un desplazamiento en la ubicación radial de la aguja seguidora de la pista.
