ABSTRACT:
A data storage device is provided that is suitable for use under the environment where mechanical shock is frequently applied. The data storage device includes plural storage units as closed structures each of which houses a storage medium therein, the storage medium being capable of moving relative to a head for access, an external force detection portion for outputting signals corresponding to external forces applied to the storage units in plural directions, and a controller for controlling the storage units. The storage units are arranged in such a manner that the storage units are different from one another in a direction of relative movement between the storage medium and the head, and the controller selectively makes one or more of the storage units perform an access operation in accordance with the signal outputted from the external force detection portion.
