Abstract

LA INVENCION ESTA RELACIONADA CON UN SOPORTE DE DATOS EN FORMA DE CD (1), QUE PUEDE ESCRIBIRSE UNA O VARIAS VECES. EL CD (1) ESTA COMPUESTO DE UN CUERPO DE CD EN FORMA CIRCULAR CON UNA CAPA SOPORTE DE INFORMACION (3) Y PRESENTA UN CHIP (12) Y UN ELEMENTO DE ACOPLAMIENTO DE CD (11) PARA LA TRANSMISION SIN CONTACTO DE DATOS ENTRE EL CHIP (12) Y UN EQUIPO DE PROCESAMIENTO DE DATOS. EL ELEMENTO DE ACOPLAMIENTO DE CD (11) PUEDE LLEVARSE A CABO COMO BOBINA, COMO SUPERFICIE DE ACOPLAMIENTO ELECTROSTATICO O COMO ELEMENTO OPTICO DE ACOPLAMIENTO. PARA LA LECTURA DE LA INFORMACION INSERTADA EN LA CAPA SOPORTE DE INFORMACION (3) DEL CD (1), ESTE PUEDE COLOCARSE EN UN LECTOR DE CD. EL LECTOR DE CD DISPONE DE UN ELEMENTO OPTICO DE ACOPLAMIENTO (51) QUE DE ACUERDO CON EL ELEMENTO DE ACOPLAMIENTO DE CD (11) TAMBIEN SE CONFIGURA COMO BOBINA, COMO SUPERFICIE ELECTROSTATICA DE ACOPLAMIENTO O COMO ELEMENTO OPTICO DE ACOPLAMIENTO Y ENVIA DATOS AL ELEMENTO DE ACOPLAMIENTO DE CD (11) O RECIBE LOS DATOS DE ESTE. EN UNA VARIANTE DE LA INVENCION EL ELEMENTO DE ACOPLAMIENTO DE CD (11) NO ESTA INTEGRADO EN EL CUERPO DE CD, SINO EN UNA PLAQUITA DE COMPRESION (65) DEL LECTOR DE CD QUE GIRA JUNTO CON EL CD (1) Y ENTRA EN CONTACTO CON LAS SUPERFICIES DISPUESTAS PARA LA GENERACION DE UNA CONEXION CONDUCTORA DE ELECTRICIDAD AL CHIP (12) DEL CD (1).
