Abstract
Se describe un aparato de grabado para una tarjeta de memoria SD que tiene una pluralidad de archivos EPUBxxx.KEY grabados en este, cada archivo tiene una pluralidad de areas de entrada Clave y Regla, y un archivo SD_ EPUB.MMG se lee del medio de grabado antes de la escritura de los datos. Un mapa de bitios en SD_EPUB.MMG muestra para cada archivo EPUBxxx.KEY si el archivo EPUBxxx.KEY tiene al menos un area de Entrada Clave y Regla no en uso, o si todas las areas de Entrada Clave y Regla estan en uso. Con base en el mapa de bitios en el archivo SD_EPUB.MMG leido, el aparato de grabacion abre el EPUB#u.KEY que tiene un area de Entrada Clave y Regla sin usar y escribe datos en el area de Entrada Clave y Regla sin usar en el archivo. Si todas las areas de Entrada Clave y Regla en EPUB#u.KEY estan en uso como resultado de la escritura de los datos, el aparato de grabacion actualiza el mapa de bitios en SD_ EPUB.MMG.
