Abstract

Un portador de información en forma de disco, provisto de una pista de información, la cual es en espiral o está compuesta de círculos concéntricos y consta de bloques de altura constante separados por espacios intermedios, correspondiendo, la variación en las longitudes de los bloques y/o de los espacios intermedios, a la información, caracterizado por que la información está compuesta de elementos de información parcial (por ejemplo, cuadros individuales de una película) los cuales en sí mismos forman unidades de información a las cuales se añaden, para reconocerlas, señales en código, para que se reconozca y/o se lea tal unidad de información, ocupando cada unidad de información, junto con la señal en código asociada, un círculo completo o semi-círculo de la pista de información, o una parte fraccionaria unitaria de tal círculo o semi-círculo, mientras que todas las señales en código están dispuestas en el portador de información, dentro de un o algunos sectores de un círculo.
