Abstract

LA PRESENTE INVENCION SE REFIERE A UN ELEMENTO DE ALMACENAMIENTO DE DATOS QUE PUEDEN REESCRIBIRSE (10) QUE COMPRENDE VARIAS AREAS DE ALMACENAMIENTO DE DATOS (12) SEPARADAS DIRIGIBLES PARA GRABAR Y ALMACENAR DATOS Y VARIAS AREAS DE NO-ALMACENAMIENTO DE DATOS (15) INTERCALADAS ENTRE OTRAS ADYACENTES A LAS AREAS DE ALMACENAMIENTO DE DATOS DIRIGIBLES PARA GRABAR SEÑALES QUE NO REPRESENTAN DATOS, EL ELEMENTO DE ALMACENAMIENTO ESTA ADAPTADO PARA EXPLORARSE EN UNA DIRECCION SOBRE LAS AREAS DE ALMACENAMIENTO. SEGUN LA INVENCION EL ELEMENTO DE ALMACENAMIENTO ESTA CARACTERIZADO EN QUE UNA DE LAS AREAS DE DATOS DIRIGIBLES CONTIENE INDICIOS LEGIBLES DE UNA PRIMERA MAQUINA QUE INDICAN QUE EL ELEMENTO DE ALMACENAMIENTO CONTIENE DATOS QUE NO SE VAN A CAMBIAR DE NINGUN REGISTRO DE DATOS ORIGINAL, OTRA DE LAS AREAS DE DATOS DIRIGIBLES CONTIENE INDICIOS LEGIBLES DE UNA SEGUNDA MAQUINA QUE INDICAN SI EL ELEMENTO DE ALMACENAMIENTO HA SIDO BORRADO DE DATOS COMPLETAMENTE O NO, Y CADA UNA DE LAS ZONAS DE NO ALMACENAMIENTO DE DATOS CONTIENE INDICIOS LEGIBLES DE UNA TERCERA MAQUINA QUE INDICAN SI PUEDE ESCRIBIRSE O NO EN UNA DE LAS AREAS ADYACENTES RESPECTIVAS DE ALMACENAMIENTO DE DATOS DIRIGIBLES. LA INVENCION TAMBIEN SE REFIERE A UN SISTEMA DE ALMACENAMIENTO DE DATOS QUE CONTIENE UN ELEMENTO DE ALMACENAMIENTO DE DATOS QUE PUEDEN VOLVERSE A ESCRIBIR COMO ANTERIORMENTE SE HA EXPUESTO Y A UN METODO PARA OPERAR CON ESTE SISTEMA DE ALMACENAMIENTO DE DATOS.
