Title
(EN) DATA RECORDING WRITE STRATEGY OPTIMISATION
(FR) OPTIMISATION DE LA STRATEGIE D'ECRITURE POUR L'ENREGISTREMENT DE DONNEES
Abstract
(EN) The present invention relates to determining at least one write strategy, using a write strategy model comprising first and second parameters, for recording data on a recording medium comprising, providing at least one set of randomised first parameters, (102, step 202), writing at least one test data, 104, pattern by using said at least one set of first randomised first parameters, (102), (106, step 204), reading the recorded test data pattern, (108, step 206) and calculating a set of second parameters, (114),(112, step 208), based on said read test data pattern (110) and the at least one set of first randomised parameters, (102). From the calculated set of second parameters, (114) and the real data to be recorded, 118, sets of first parameters (120) are calculated, (step 210). The real data (118) are recorded (122, step 212) by using the chosen write strategy model.
(FR) La présente invention concerne un procédé permettant de déterminer au moins une stratégie d'écriture, à l'aide d'un modèle de stratégie d'écriture comportant des premiers et des seconds paramètres, afin d'enregistrer des données sur un support d'enregistrement. Ce procédé comprend les étapes consistant à créer au moins un ensemble de premiers paramètres randomisés (102, étape 202), à écrire au moins une combinaison de données d'essai (104) au moyen dudit au moins un ensemble de premiers paramètres randomisés(102), (106, étape 204), à lire la combinaison de données d'essai enregistrée (108, étape 206) et à calculer un ensemble de deuxièmes paramètres (114), (112, étape 208) sur la base de ladite combinaison de données d'essai lue (110) et du au moins un ensemble de premiers paramètres randomisés (102). Des ensembles de premiers paramètres (120) sont calculés (étape 210) à partir de l'ensemble de deuxièmes paramètres (114) calculé et des données réelles à enregistrer (118). Ces données réelles (118) sont enregistrées (122, étape 212) à l'aide du modèle de stratégie d'écriture choisi.
