Abstract

SE PRESENTA UN SISTEMA PARA EVITAR QUE LOSREPRODUCTORES DE DISCOS SEAN UTILIZADOS CON SOFTWARE NO AUTORIZADO. EL CODIGO DE SEGURIDAD SE ALMACENA A TRAVES DE LA MODULACION DE UNA DESVIACION DE LA POSICION FISICA DE UNA PLURALIDAD DE BITS DE DATOS A PARTIR DE UNA POSICION NOMINAL DE PISTA. UNA CABEZA LECTORA OPTICA DE DOS PARTES SUMINISTRA UNA SEÑAL DE RF QUE SE CORRESPONDE CON LA PRESENCIA DE UNA MODULACION DE DESVIACION FISICA. LA SEÑAL DE RF ESTA PRESENTE CUANDO HAY UNA DESVIACION FISICA DE LOS BITS DE DATOS QUE DEFINE UN PRIMER ESTADO LOGICO Y LA AUSENCIA DE LA SEÑAL DE RF DEFINE UN SEGUNDO ESTADO LOGICO. UN CODIGO DE SEGURIDAD DIGITAL SE CODIFICA Y SE DESCODIFICA DE ESTA MANERA. TAMBIEN SE PRESENTA UN SISTEMA PARA CODIFICAR UN CODIGO DE SEGURIDAD A TRAVES DE LA MODULACION DE LA DESVIACION FISICA DE UNA PLURALIDAD DE BITS DE DATOS DE LA POSICION DE LA PISTA NOMINAL.
