Abstract
The storage device reduces vibration accompanied by high-speed rotation of a storage media, and raises reliability as well. In a stationary position of amass object, each magnetic pole of the movable portion magnet is disposed so that their position is provided in opposite relation to each magnetic pole of a fixed portion magnet, and each magnetic pole of a movable portion magnet and the fixed portion magnet is opposite a different magnetic pole with respect to each other. An attraction force:F,and a repulsion force:F,between facing (or confronting) magnetic pole can be used efficiently, and a large vibration energy or inertia force can be obtained by a small-sized magnet.
