Title (EN) DUAL ACTUATOR HARD DISK DRIVE
(FR) LECTEUR DE DISQUE DUR À DOUBLE ACTIONNEUR
Abstract:
(EN) Described are systems and methods for implementation in relation to hard disk drives. The disclosure is direct, at least in part, to a method for writing data in a multiple actuator multiple disk system, and the multiple actuator disk system for performing that method. The method comprises receiving the data and dividing the data into at least a first predetermined portion and a second predetermined portion. The method also includes and writing the first predetermined portion of the data onto a first disk surface of the multiple actuator multiple disk system using a first actuator of the multiple actuators while writing the second predetermined portion of the data onto a second disk surface of the multiple actuator multiple disk system using a second actuator of the multiple actuators.
(FR) L'invention concerne des systèmes et des procédés de mise en œuvre concernant des lecteurs de disque dur. L'invention concerne au moins partiellement un procédé d'écriture de données dans un système à disques multiples et à actionneurs multiples, ledit système à disques multiples et à actionneurs multiples étant conçu pour exécuter ledit procédé. Le procédé comprend les étapes consistant à : recevoir les données et les diviser au moins en première et seconde parties prédéterminées; et écrire la première partie prédéterminée des données sur une première surface de disque du système à disques multiples et à actionneurs multiples à l'aide d'un premier actionneur parmi les multiples actionneurs tout en écrivant la seconde partie prédéterminée des données sur une seconde surface de disque du système à disques multiples et à actionneurs multiples à l'aide d'un second actionneur parmi les multiples actionneurs.
