Abstract

REGISTRADOR OPTICO DE INFORMACION SOBRE SOPORTE EN FORMA DE DISCO. EN EL SOPORTE DE REGISTRO SE PRODUCE UNA MODULACION DE PISTA PERIODICA, CUYO PERIODO CORRESPONDE A UNA FRECUENCIA PARA LA CUAL EL ESPECTRO DE POTENCIA ALEATORIO DE LA INFORMACION CODIFICADA DIGITALMENTE A REGISTRAR, PRESENTA AL MENOS UN PUNTO DE AMPLITUD NULA, CON EL FIN DE GENERAR UNA SEÑAL DE SINCRONISMO DE LA FRECUENCIA IGUAL A LA DE REPETICION DE BITIOS DURANTE EL REGISTRO. DICHA MODULACION TIENE UNA FASE QUE VARIA DE PISTA A PISTA EN DIRECCION RADIAL CON EL FIN DE DETECTAR UNA TRANSICION NO DESEADA ENTRE PISTAS ADYACENTES DURANTE EL REGISTRO, E INTERRUMPIR EN CONSECUENCIA EL PROCESO DE REGISTRO PARA NO INSCRIBIR SOBRE LA PISTA ADYACENTE.
