Abstract
A hard disk drive is made small in size, large in storage capacity and high in data reading/writing speed. Two actuator blocks ( ) are fixed to a sleeve A of a first pivot and sleeve ( B) of a second pivot, respectively. Position of magnetic heads to be accessed to different magnetic disks are controlled independently by the actuator block basis. Therefore, it is possible to distribute the reading/writing processing to the plurality of magnetic disks and perform these processing in parallel, to thereby increase the data reading/writing speed while increasing the storage capacity.
