Abstract

Perfeccionamientos en aparatos de reproducción de videodisco, del tipo que se dispone para utilizarse con una caja de disco, caracterizado porque dichos aparatos tienen una ranura de entrada en la cual se inserta la caja del disco a lo largo de un trayecto para cargar un disco protegido en su interior, un plato giratorio montado en la caja para centrar y sostener el disco cargado; medios montados en la caja para hacer girar el plato giratorio; un captor de señal para recuperar la información previamente grabada desde el disco sostenido por el plato giratorio durante la reproducción; un carro para sostener el captor de la señal; y medios para trasladar el carro durante la reproducción a lo largo de un segundo trayecto que queda prácticamente paralelo al trayecto de la caja del disco a una velocidad en correlación con la velocidad de rotación del plato giratorio.
