Title (EN) A METHOD AND SYSTEM FOR PROTECTING DATA STORED ON AN OPTICAL DISC
(FR) PROCEDE ET SYSTEME POUR LA PROTECTION DE DONNEES ENREGISTREES SUR UN DISQUE OPTIQUE
Abstract:
(EN) The invention relates to a system and method of protecting data stored on an optical disc, said method comprising the steps of: - replicating (101) the data of said optical disc to a first storage device, - reading out (102) the data from said optical disc, - generating (103), from a quality parameter of the read out data, an output signal indicating a good or low quality of said optical disc, and - writing (104) the data of said first storage device to a second storage device if said output signal indicates a low quality.
(FR) Système et procédé pour la protection de données enregistrées sur un disque optique. Le procédé comprend les étapes suivantes: - reproduction (101) des données vers un premier dispositif de stockage, - lecture (102) des données sur le disque optique, production (103), à partir d'un paramètre de qualité des données lues, d'un signal de sortie indiquant une qualité satisfaisante ou faible du disque optique, et - écriture (104) des données du dispositif de stockage sur un second dispositif de stockage si le signal de sortie indique une faible qualité.
