Abstract
Un aparato para leer un soporte de registro en forma de disco sobre el cual está registrada información de video de acuerdo con una estructura detectable ópticamente en pistas sustancialmente paralelas, cuyo aparato está provisto de una unidad de lectura óptica que tiene una fuente de radiación para emitir un haz de radiación de lectura, un detector de lectura para detectar la información contenida en el haz de radiación de lectura después de cooperar con el soporte de registro, y un elemento de deflexión que coopera con el haz de radiación de lectura para variar la posición de exploración radial sobre el soporte de registro.
