Abstract

Perfeccionamientos en sistemas de registro y reproducción de gran densidad en discos de material termoplástico , caracterizados porque dichos discos tienen un surco espiral de anchura constante en una superficie del mismo, siendo la separación de centro a centro de espiras sucesivas de dicha espiral prácticamente constante e independiente de la información registrada, conteniendo dicho surco una pista de información constituida por variaciones en la geometría del fondo del surco representativas de la información registrada.
