Abstract

METODO PARA GESTIONAR DATOS EN UNA LIBRERIA DE MEMORIA, Y JERARQUIA DE ALMACENAMIENTO DE DATOS ADECUADA AL MISMO. LA JERARQUIA DE ALMACENAMIENTO DE DATOS INCLUYE UNA LIBRERIA OPTICA Y UNA ESTANTERIA DE MANEJO MANUAL. LA LIBRERIA OPTICA INCLUYE AL MENOS UNA UNIDAD DE DISCO OPTICO Y UNA PLURALIDAD DE CELDAS PARA EL ALMACENAMIENTO DE LOS DISCOS OPTICOS. LA LIBRERIA OPTICA INCLUYE ASIMISMO UN ELEMENTO PARA TRANSFERIR LOS DISCOS OPTICOS DE LAS CELDAS A LAS UNIDADES DE DISCO OPTICAS EN LA LIBRERIA. EL PROCESADOR PRINCIPAL, TRAS DETERMINAR LOS DATOS A ALMACENAR, ES REQUERIDO PARA SU ALMACENAMIENTO EN LA LIBRERIA OPTICA, PRIMERO COMPRUEBA PARA DETERMINAR SI LOS DISCOS QUE ESTAN EN LA LIBRERIA OPTICA TIENEN CAPACIDAD PARA EL ALMACENAMIENTO DE TALES DATOS. SI EXISTE DICHA CAPACIDAD EN LA LIBRERIA OPTICA NO HAY PROBLEMA Y LOS DATOS SON ALMECANADOS AHI. SI LA LIBRERIA OPTICA NO TIENE LA CAPACIDAD REQUERIDA, O SI EL OPERADOR DEL SISTEMA ASI LO DECIDE, EL DISCO OPTICO DE LA LIBRERIA OPTICA QUE HA SIDO AL MENOS RECIENTEMENTE MONTADO EN UNA UNIDAD DE DISCO OPTICA PASA DE LA LIBRERIA OPTICA A LA ESTANTERIA DE MANEJO MANUAL. ENTONCES PUEDE SER ALIMENTADO OTRO DISCO EN LA LIBRERIA OPTICA PARA EL ALMACENAMIENTO DE LOS DATOS REQUERIDOS.
