Abstract

Perfeccionamientos en las hojas magnetofónicas que presentan en el anverso inscripciones relativas al contenido sonoro de la hoja y en el reverso una película o capa magnetofónica, las cuales se fijan sobre la tabla de un aparato magnetofónico provisto de varias cabezas magnéticas que van explorando la película magnetofónica dispuesta en el dorso de la hoja, fijando esta hoja a la tabla pro medio de espigas dispuestas en la tabla que penetran en agujeros practicados en las hojas, caracterizados porque uno de los agujeros de ajuste de la hoja se hace en forma de ranura dispuesta en la línea central de la película magnetofónica y de ancho exactamente igual al diámetro de la correspondiente espiga de ajuste fijada en la tabla.
