Abstract

EN UN CD ESTA GRABADA EN LA LLAMADA PISTA DE ENTRADA EL SUMARIO DEL DISCO. LOS DATOS DEL SUMARIO ESTAN DIVIDIDOS EN VARIOS BLOQUES. PARA FINES DE REDUNDANCIA ESTAN GRABADOS VARIOS BLOQUES CON EL MISMO CONTENIDO DE DATOS SOBRE EL CD UNOS DESPUES DE OTROS. UN APARATO REPRODUCTOR DE CD LEE LA TOTALIDAD DEL SUMARIO, LEYENDO TODOS LOS BLOQUES, INCLUSO LOS REDUNDANTES UNO DESPUES DE OTRO, MOVIENDO UN DISPOSITIVO EXPLORADOR A LO LARGO DE LA PISTA DE DATOS EN ESPIRAL. CON EL FIN DE REDUCIR EL TIEMPO PARA LA LECTURA DEL SUMARIO, EL DISPOSITIVO DE EXPLORACION EN LA LECTURA DE LOS DATOS DEL SUMARIO SALTA UNA PISTA HACIA AFUERA O HACIA ADENTRO, CUANDO HA LEIDO UN BLOQUE. MEDIANTE ESTA MEDIDA YA NO SE LEEN TODOS LOS BLOQUES REDUNDANTES, SINO SOLO UNA PARTE PEQUEÑA DE ELLOS. POR TANTO, SE PUEDE REDUCIR NOTABLEMENTE EL TIEMPO PARA LA LECTURA Y EL ALMACENADO DE LOS DATOS DEL SUMARIO.
