Title
(EN) DATA STORAGE DEVICE AND METHOD FOR OPERATING A DATA STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE DE DONNEES ET PROCEDE POUR L'EXPLOITATION D'UN DISPOSITIF DE STOCKAGE DE DONNEES
Abstract
(EN) A data storage device comprises a storage medium, at least one probe designed for creating indentation marks in the storage medium, a control unit designed for creating a control parameter (CTRL) acting on the probe resulting in the creation of one indentation mark. The control unit is further designed for modifying the control parameter (CTRL), if at least a given number of consecutive indentation marks with a given minimum distance between each other should be created. According to the method the control parameter (CTRL) is modified if at least a given number of consecutive marks with a given minimum distance between each other should be created.
(FR) La présente invention a trait à un dispositif de stockage de données comportant au moins un support de stockage, au moins une sonde destinée à la création d'empreintes dans le support de stockage, une unité de commande destinée à la création d'un paramètre de commande (CTRL) agissant sur la sonde grâce à la création d'une empreinte. L'unité de commande est en outre destinée à la modification du paramètre de commande (CTRL), si au moins un nombre déterminé d'empreintes consécutives avec une distance minimale entre elles devaient être créées. Selon le procédé, le paramètre de commande (CTRL) est modifié si au moins un nombre d'empreinte consécutives à une distance minimale entre elles autres devaient être créées.
