Abstract
Perfeccionamiento en dispositivos saltadores de surcos ppara un apparato de video disco, del tipo que se dispone en un sistema ppara recuperar información previamente grabada de un disco que tiene una pista de información espiral por medio de una aguja seguidora de la pista cuando se establece la velocidad relativa de la agua/disco; donde el funcionamiento normal del sistema comprende detectar la información previamente grabada a lo largo de vueltas o espiras sucesivas de la pista espiral en una progresión regular hacia una extremidades, cparacterizados porque comprenden un carro sujeto a movimiento traslatorio en correlación con molimientos radial de la aguja de seguimiento de la pista durante la reproducción, cuyo carro tiene una abertura en una pared inferior del mismo, un brazo de aguja que tiene un eje geométrico longitudinal y lleva la aguja seguidora de la pista en un extremo del brazo de la aguja contrario al extremo del carro; permitiendo los medios de sujeción elásticos que la aguja seguidora de la pista sobresalga a través de la abertura cuando el brazo de la aguja desciende durante la reproducción, un elemento magnético sujeto al brazo de la aguja cerca de uno de sus extremos, un electroimán ppara proporcionar un campo magnético controlable de una polaridad dada cunado se activa, medios ppara montar el electroimán al carro en las proximidades del elemento magnético; y medios para activar de una forma selectiva el electroimán y producir un desplazamiento en el lugar radial de la aguja seguidora de la pista.
